Introduction:
c program to concatenate two strings using pointers
I have used Code::blocks 12 compiler for debugging purpose. But you can use any C programming language compiler as per your availability.
Write C program to Concatenate Two Strings Using Pointers
#include <stdio.h>
#define MAX_SIZE 100 // Maximum string size
int main()
{
char str1[MAX_SIZE], str2[MAX_SIZE];
char * s1 = str1;
char * s2 = str2;
// Inputting 2 strings from user
printf("Enter 1st string: ");
gets(str1);
printf("Enter 2nd string: ");
gets(str2);
// Moving till the end of str1
while(*(++s1));
// Coping str2 to str1
while(*(s1++) = *(s2++));
printf("Concatenated string: %s", str1);
return 0;
}
