新手c语言问题求教谢谢

Question

2 将下面C语言风格的程序改为C++风格的程序。

/* 程序改写 */

#include <stdio.h>

int add(int a,int b);

int main()

{

        int x,y,sum;

        printf("Please input x and y:\n");

        scanf("%d%d",&x,&y);

        sum=add(x,y);

        printf("%d+%d=%d\n",x,y,sum);

        return 0;

}

int add(int a,int b)

{

        return a+b;

}

 

Answer 1

// #include <stdio.h>
#include <iostream>

using namespace std;

int add(int a, int b);

int main(void) {
	int x, y, sum;

	// printf("Please input x and y:\n");
	cout << "Please input x and y:" << endl;

	// scanf("%d%d", &x, &y);
	cin >> x >> y;

	sum = add(x, y);

	// printf("%d+%d=%d\n", x, y, sum);
	cout << x << " + " << y << " = " << sum << endl;

	return 0;

}

int add(int a, int b) {
	return a + b;

}

C++，原c代码还留着，自己对照着看吧！
