string length in c without using strlen and string header
#include <stdio.h>
// function for string length
int string_length(char str[])
{
int i;
// you can use while loop
for( i = 0; str[i] != '\0';i++);
return i;
}
int main()
{
// declaring character array
char your_name[20]; // you can change the maximum size of string
printf("Type you full Name : ");
// taking input from user
gets(your_name);
// using string length function
int length = string_length(your_name);
// printing string length
printf("\nLength of your name (%s) is : %d \n\n",your_name,length);
