Operator in C programming language with example

In this tutorial, we discuss Operator in C programming language with the example.

C programming operators

C language provides a rich set of operators to manipulate variables. We can divide all the C programming operators into the following groups:

• Arithmetic Operators
• Assignment Operators
• Relational Operators
• Unary Operators
• Logical Operator
• Bitwise operator

#include <stdio.h>
#include <stdlib.h>

int main()
{ //+,-*,./%
    //printf("Hello world!\n");
    int a,b;
    int c,d,e,f,g;
    printf("Enter a valua to a\n");
    scanf("%d",&a);
    printf("Enter a valua to b\n");
    scanf("%d",&b);
    c=a+b,
    d=b-a;
    e=a*b;
    f=b/a;
    g=b%a;
    printf("a+b value is :%d \n",c);
    printf("a-b value is :%d \n",d);
    printf("a*b value is :%d \n",e);
    printf("a/b value is :%d \n",f);
    printf("a%b value is :%d \n",g);
    getch();
    return 0;
}

C Assignment Operator

In C Programming, the assignment operator is used for assigning a significant value to a variable. Equal to(=) is a mostly known assignment operator in algebra.

The following table list the assignment operators in C language

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int a,b,x,y,z,m,n,p,q;
    printf("Enter a valua to a\n");
    scanf("%d",&a);
    printf("Enter a valua to b\n");
    scanf("%d",&b);
    x=a+=b;
    printf("a+=b value is :%d \n",x);
    y=a-=b;
    printf("a-=b value is :%d \n",y);
    z=a*=b;
    printf("a*=b value is :%d \n",z);
    m=a/=b;
    printf("a/=b value is :%d \n",m);
    n=a%=b;
    printf("a%=b value is :%d \n",n);
    p=a&=b;
    printf("a&=b value is :%d \n",p);
     q=a^=b;
    printf("a^=b value is :%d \n",q);

    return 0;
}

When the above code compiled and executed, it produced the following result

Enter a value to a
Enter a value to b
36
Enter a value to b
12
a+=b value is : 48
a-=b value is :24
a*=b value is :288
a/=b value is :24
a&=b value is :0
a^=b value is :12

C Relational Operators

A relational operator compares the relationship between two variables(operands). relational operators perform based on boolean expression and return either true(1) or false(0).

The following table list the relational operators in C language

#include <stdlib.h>
int main()
{
    int x=10,y=10,z=20;
    printf("x is equal to y :%d\n",x==y); //true
    printf("x is equal to z :%d\n",x==z); //false
    printf("y is equal to z :%d\n\n",y==z); //false

    printf("x is greater than to y :%d\n",x>y); //false
    printf("x is greater than to z :%d\n",x>z); //false
    printf("y is greater than to z :%d\n\n",y>z); //false

    printf("x is less than to y :%d\n",x<y); //false
    printf("x is less than to z :%d\n",x<z); //true
    printf("y is less than to z :%d\n\n",y<z); //true

    printf("x is less than or equal to y :%d\n",x<=y); //true
    printf("x is less than or equal to z :%d\n",x<=z); //true
    printf("y is less than or equal to z :%d\n\n",y<=z); //true

    printf("x is greater than or equal to y :%d\n",x>=y); //true
    printf("x is greater than or equal to z :%d\n",x>=z); //false
    printf("y is greater than or equal to z :%d\n\n",y>=z); //false

    printf("x is not equal to y :%d\n",x!=y); //false
    printf("x is not equal than to z :%d\n",x!=z); //true
    printf("y is not equal to z :%d\n\n",y!=z); //true

    printf("End the program");
    getch();
    return 0;
}

When the above code compiled and executed, it produces the following result

x is equal to y: 1
x is equal to z :0
y is equal to z :0

x is greater than to y :0
x is greater than to z :0
y is greater than to z :0

x is less than to y :0
x is less than to z: 1
y is less than to z: 1

x is less than or equal to y: 1
x is less than or equal to z: 1
y is less than or equal to z: 1

x is greater than or equal to y: 1
x is greater than or equal to z :0
y is greater than or equal to z :0

x is not equal to y :0
x is not equal than to z: 1
y is not equal to z: 1

End the program

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{//== != < > <= >=
    int a,b;
    a=20,b=15;
    if(a<b){
            printf("a less than b\n");
    }else{
    printf("a greater than or equal to b\n");
    }
    if(a>b){
            printf("a greater than b\n");
    }else{
    printf("a less than or equal to b\n");
    }
    if(a<=b){
            printf("a less than or equal to b\n");
    }else{
    printf("a greater than b\n");
    }
    if(a>=b){
            printf("a greater than or equal to b\n");
    }else{
    printf("a less than b");
    }
    if(a==b){
            printf("a equal to b\n");
    }else{
    printf("a not equal to b\n");
    }
    if(a!=b){
            printf("a not equal to b\n");
    }else{
    printf("a equal to b\n");
    }
    //printf("Hello world!\n");
    return 0;
}

When the above code compiled and executed, it produces the following result

a less than or equal to b
a greater than b
a greater than b
a greater than or equal to b
a not equal to b
a not equal to b

C unary Operator

The following table list the unary operators in C language

How  works unary operator in C language

Program

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x=10,y=5,z;
    z=+x;
    printf("+x value is :%d\n",z);//Unary plus

    z=-y;
     printf("-y value is :%d\n",z);//Unary minus

     z=++x;
     printf("++x value is :%d\n",z);//prefix increment

     z=y++;
     printf("y++ value is :%d\n",z);//postfix increment

     z=--x;
     printf("--x value is :%d\n",z);//prefix decrement

     z=y--;
     printf("y-- value is :%d\n",z);//postfix decrement

    printf("End the program\n");
    getch();
    return 0;
}

When the above code compiled and executed, it produces the following result

+x value is :10
-y value is :5
++x value is :11
y++ value is :6
--x value is 10
y-- value is :6
End the program

C Logical Operators

The logical operator performs based on boolean expression, return either true or false.

The following table list the logical operators in C language

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int age=20;
    if(age<=18 && age >=13){
    printf("you are a teenager\n");
    }else{
    printf("you are old or child\n");
    }
    if(age>=18 || age <=13){
    printf("you are not a teenager\n");
    }else{
    printf("you are a yanger\n");
    }
    return 0;
}

you are a teen ager
you are not teenager
