C Program to check the length of string | C Programming

Strings 

The way a group of integers can be stored in an integer array, similarly a group of characters can be stored in a character array. Character arrays are many a time also called strings. Many languages internally treat strings as character arrays, but somehow conceal this fact from the programmer. Character arrays or strings are used by programming languages to manipulate text such as words and sentences.

A string constant is a one-dimensional array of characters terminated by a null ( ‘\0’ ). For example,

char name[ ] = { 'H', 'A', 'E', 'S', 'L', 'E', 'R', '\0' } ;

#include<stdio.h>
int main()
{char str[50]; int i, count=0;
printf("Enter a line:-\n");
gets(str);
for(i=0;str[i]!='\0';i++)
{count ++;}
printf("The length of the string is %d.",count);
return 0;
}
