C String Substring

In this section, you will learn how to get the substring from a string in C. You can see in the given example, a string and a method substring() is created. Inside the method, we have declared the variables i and j to select the part of the string in order to get the substring. On calling the method substring(6,19,ch), you will get the substring from the specified string. Here 6 and 19 are the starting and ending index values of the string.

Here is the code:

SUBSTRIN.C


#include <stdio.h>

#include <conio.h>

void substring(int i, int j, char *ch) {

  printf("The substring is: %.*s\n", j - i, &ch[i]);

}

void main() {

  char ch[] = "Where there is will,there is a way.";

  clrscr();

  substring(6, 19, ch);

  getch();

}

Output will be displayed as:
