Continue statement in C programming language

Continue statement in C programming language

C program continue statement

We will get to know the uses of Continue statement in C programming language in this tutorial (using for loop and while loop) – it controls the flow of control of loops  in C language

Description

Continue is a keyword in the C language (some time called as a statement because ending with the semicolon)which is used to control the flow of loops.

Typically, this statement can be used inside of the while and for loop.

The continue statement provides the option to skip the current iteration(skip some statements) of the flow of control to the following loops until the flow of control exits the loops.

The syntax of the continue

continue statement in for loop

Program 1

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

int main()
{
    int i;
    for(i=1; i<=10; i++)
    {
        if(i==5){
            printf("Skipped this value :%d\n",i);
            continue;
        }
        printf("%d\n",i);
    }
    printf("End of loop\n");
    getch();
    return 0;
}

 

When the above code is compiled and executed, it will produce the following results

1
2
3
4
skipped value :5
6
7
8
9
10
End of loop

 

When this program is executed, number 5 skipped by continue statement in for loop of C

Program 2

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int num;
    int sum=0;
    int i,n;
    printf("Enter any number \n");
    scanf("%d",&n);

    for(i=1; i<=n; i++){
            printf("Enter Number :%d\n",i);
            scanf("%d",&num);
            if(num==20){
                continue;
            }
           sum=sum+num;
        }
        printf("Total value is :%d\n",sum);
    printf("End of program");
    getch();
    return 0;
}

 

When the above code is compiled and executed, it will produce the following results

Enter any number 5 
Enter number :1 
10 
Enter number :2 
20
Enter number :3 
30 
Enter number :4 
40 
Enter number :5 
50
Total value is :130 
End of program

Number 20 skipped by continue statements from the addition

Program 3

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int i=1;
    while(i<=10){
        if(i==6){
            printf("Skipped value :%d\n",i);
            i++;
               continue;
        }
        printf("value %d\n",i);
        i++;
    }
    printf("End of loop\n");
    getch();
    return 0;
}

 

When the above code is compiled and executed, it will produce the following results

value 1
value 2
value 3
value 4
value 5
Skipped value :6
value 7
value 8
value 9
value 10
End of loop

 

When this program is executed, number 6 skipped the continue statement in for loop

Program 4

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int num;
    int sum=0;
    int i,n;
    printf("Enter any number \n");
    scanf("%d",&n);
    i=1;
    while(i<=n){
            printf("Enter Number :%d\n",i);
            scanf("%d",&num);
            if(num==25){
                continue;
                ++i;
            }
           sum=sum+num;
           ++i;
        }
        printf("Total value is :%d\n",sum);
    printf("End of program\n");
    getch();
    return 0;
}

 

When the above code is compiled and executed, it will produce the following results

Enter any  number
5
Enter number :1
10
Enter number :2
15
Enter number :3
20
Enter number :4
25
Enter number :5
30
Total value is :110
End of program

When this program is executed, number 25 is skipped from calculating total by continue statement in for loop
