Write a C program to concatenate two strings using pointers.

Program Code:

#include<stdio.h>

#define SIZE 20

void concat(char *,char *);

int main()

{

char string1[SIZE]="\0",string2[SIZE]="\0";

printf("Enter String 1:\n");

gets(string1);

printf("Enter String 2:\n");

gets(string2);

concat(string1,string2);

return 0;

}

void concat(char *str1,char *str2)

{

char *conc=str1;

while(*str1!='\0')

str1++;

*str1=' ';

++str1;

while(*str2!='\0')

{

*str1=*str2;

str1++;

str2++;

}

*str1='\0';

printf("Concatenated String:\n");

puts(conc);

}
