C Program To Find Length Of A String

C program to find the length of a string; Through this tutorial, we will learn how to write a program to find a length of a string using for loop, function, recursion, and built-in method in c.

Programs To Find Length Of A String in C

  • C Program To Find Length Of A String using For Loop
  • C Program To Find Length Of A String using Function
  • C Program To Find Length Of A String using Recursion
  • C Program To Find Length Of A String using strlen() function

C Program To Find Length Of A String using For Loop

#include <stdio.h>
 
int main()
{
    char s[1000];  
    int i;
 
    printf("Enter any string: ");
    gets(s);
    for(i=0; s[i]!='
#include <stdio.h>
int main()
{
char s[1000];  
int i;
printf("Enter any string: ");
gets(s);
for(i=0; s[i]!='\0'; i++);
printf("Length of '%s' = %d",s,i);
return 0;
}
'; i++); printf("Length of '%s' = %d",s,i); return 0; }

The output of the above c program; as follows:

Enter any string: programming
Length of 'programming'= 11

C Program To Find Length Of A String using Function

int stringlength(char *s)
{
	int i;
    for(i=0; s[i]!='
int stringlength(char *s)
{
int i;
for(i=0; s[i]!='\0'; i++);
return i;
}
int main()
{
char s[1000];  
int length;
printf("Enter any string: ");
gets(s);
length=stringlength(s);
printf("Length of '%s' = %d",s,length);
return 0;
}
'; i++); return i; } int main() { char s[1000]; int length; printf("Enter any string: "); gets(s); length=stringlength(s); printf("Length of '%s' = %d",s,length); return 0; }

The output of the above c program; as follows:

Enter any string: hello
Length of 'hello' = 5

C Program To Find Length Of A String using Recursion

int stringlength(char *s,int i)
{
    if(s[i]=='
int stringlength(char *s,int i)
{
if(s[i]=='\0')
return i;
stringlength(s,++i);
}
int main()
{
char s[1000];  
int length;
printf("Enter any string: ");
gets(s);
length=stringlength(s,0);
printf("Length of '%s'= %d",s,length);
return 0;
}
') return i; stringlength(s,++i); } int main() { char s[1000]; int length; printf("Enter any string: "); gets(s); length=stringlength(s,0); printf("Length of '%s'= %d",s,length); return 0; }

The output of the above c program; as follows:

Enter any string: using recursion
Length of 'using recursion'= 15

C Program To Find Length Of A String using strlen() function

#include <string.h>
 
 
int main()
{
    char s[1000];  
    int length;
 
    printf("Enter any string: ");
    gets(s);
    length=strlen(s);
    printf("Length of '%s'= %d",s,length);
 
    return 0;
}

The output of the above c program; as follows:

Enter any string: hello
Length of 'hello' = 5
