Length of string in C language by R4R Team

Here we find the length of the given string without any use of the predefined library.

Example-
strinf is "r4r_string"
Length is : 10

program-

#include< stdio.h>
int main()
{
char ch[20];
int len=0,i=0;
printf("Enter string\n");
scanf("%s",&ch);
while(1)
{
if(ch[i++]!='')
len++;
else
break;
}
printf("Length of the string is %d",len);
}


output-

Enter string
Mystring
Length of the string is 8

-In this program, we firstly take an input in string(i.e, ch[20]) and run the while loop until the string terminated
-Each iteration of loop increase the value of the variable 'len'
-And at last we have a length of the string in 'len' variable which we display.
-if(ch[i++]!=''), where '' represent the end of the string.
