C Program to Find the Length of a String

#include <stdio.h>
int main()
    /* Here we are taking a char array of size
     * 100 which means this array can hold a string
     * of 100 chars. You can change this as per requirement
    char str[100],i;
    printf("Enter a string: \n");
    // '\0' represents end of String
    for(i=0; str[i]!='\0'; ++i);
       printf("\nLength of input string: %d",i);
    return 0;
