C Program to Find the Length of a String
In this article, you'll learn to find the length of a string without using strlen() function.
#include <stdio.h>
int main()
{
char s[1000];
int i;
printf("Enter a string: ");
scanf("%s", s);
for(i = 0; s[i] != '\0'; ++i);
printf("Length of string: %d", i);
return 0;
}
Enter a string: Programiz
Length of string: 9
This program asks user to enter a string and computes the length of string manually using for loop.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
