#include <stdio.h>
#include <string.h>

int main(){
	char str1[100];
	char str2[100];
	char temp[100];
	
	printf("Enter string: ");
	gets(str1);
	printf("Enter text to insert: ");
	gets(str2);
	
	//copy first string in temp variable
	memcpy(temp,str1,sizeof(str1));

	//copy second string first
	memcpy(str1,str2,strlen(str2));
	memcpy(str1+strlen(str2),temp,strlen(temp)+1);

	printf("String is: %s\n",str1);
	
	return 0;	
}
