In this tutorial, we will discuss strtok string function in C programming language

strtok() -In C programming language,strtok string function used to breaks the token into a series of the string using the delimiter.

Declaration

Required Header

the required header for strtok() String function in C Programming language

#include<string.h>

Example

In this program input string “My website, code for coding, for learning coding” is analyzed using strtok() function, delimiter comma(,) is used to separates each substring from the main string

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{

char myweb[100]="My web site, code for coding, for learning coding";
char *p;
p=strtok(myweb,",:");

while(p!=NULL)
{
    printf("%s\n",p);
    p=strtok(NULL,",:");
getch();

}
return 0;
}

 

When above program me  is compiled it will produce the following result

My web site
code for coding
for learning coding
