C Program to Find Length of a String

This is a simple program written in C programming language to find the length of a string entered by your while execution of this program.

This program will calculate the length of string without using the strlen() function. It will count the string length by using the for(i = 0; s[i] != '\0'; ++i); loop.

#include <stdio.h>
int main()
{
    char s[1000], i;

    printf("Enter a string: ");
    scanf("%s", s);

    for(i = 0; s[i] != '\0'; ++i);

    printf("Length of string: %d", i);
    return 0;
}

#include <stdio.h>

int main()

{

char s[1000], i;

printf("Enter a string: ");

scanf("%s", s);

for(i = 0; s[i] != '\0'; ++i);

printf("Length of string: %d", i);

return 0;

}
