C/C++ | Q-23

Q-23:	Write a C/C++ program to concatenate two given strings.

Using - C
#include<stdio.h>

void main() {
  char str1[1024], str2[1024];
  int i=0, j, length=0;
  printf("Enter String-1:  ");
  gets(str1);
  printf("Enter String-2:  ");
  gets(str2);

  while(str1[i] != '\0') {
    length++;
    i++;
  }

  for (j = 0; str2[j] != '\0'; ++j, ++length) {
    str1[length] = str2[j];
  }
  str1[length] = '\0';

  printf("After Concatenation:  %s",str1);
}

OUTPUT

Enter String-1:  Hello
Enter String-2:  World
After Concatenation:  HelloWorld

Using - C++
#include<iostream>
using namespace std;

int main() {
	string str1, str2, concat_result;
	cout<< "Enter String-1:  ";
	getline(cin,str1);
	cout<< "Enter String-2:  ";
	getline(cin,str2);

	concat_result = str1 + str2;

	cout<< "After Concatenation:  "<< concat_result;

	return 0;
}

OUTPUT

Enter String-1:  Anuj
Enter String-2:  Das
After Concatenation:  Anuj Das
