Count Number of space of the given string in C language

Count Number of space of the given string in C language

In this article, we will discuss the concept of the Count Number of space of the given string in C language

In this post, we are going to learn how to  count the number of spaces in  the given string in C programming language

When the above code is executed, it produces the following result

Enter a string
C program to count space of a string
Total white space:7

C code to count space of the given string using while loop

The program allows the user to enter a String and then it counts the number of white spaces in the given string using while loop in C programing language

Program 2

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

int main()
{
char str[100];
int i;
int space=0;
    printf("Enter a string\n");

    gets(str);
    i=0;
    while(i<=str[i]){
 if(str[i]==' '){
        space++;
    }
    i++;
}

printf("Total white space :%d ",space);
getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter a string
space counter code in C language
Total white space:5

 

C code to count space of the given string using do-while loop

The program allows the user to enter a String and then it counts the number of white space in the given string using do-while loop in C programing language

Program 3

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

int main()
{
char str[100];
int i;
int space=0;
    printf("Enter a string\n");

    gets(str);
    i=0;
    do{
 if(str[i]==' '){
        space++;
    }
    i++;
}while(i<=str[i]);

printf("Total white space :%d ",space);
//getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter a string
C program for count space
Total white space:4

 

Approaches

1. Declare a Caracter array as char ch[100];
2. Declare and initialize integer variables as space=0;
   
3. The user asked to enter a string
4. The given string is stored in the variable str;
5. A loop(for, while and do-while) is used to count space in the given string.
6. It is initialized as i=0, checks the condition whether i<=str[i]; and executes the loop until the given condition becomes true
7. Use an if condition to test if(str[i]==’  ‘), when the if statements is true,  The space becomes space + 1( space = space +1);
8. When it is false, terminates the loop
9. Finally, the program displays the total number of space of the given string
