Question
I asked these questions yesterday but some of them were written incorrectly. All I need is the output for these said questions. Thanks a lot :)
1.)
#include <iostream>
using namespace std;
int main()
{
int x, y;
x=10;
y=15;
if(x>=9)
{
x=x+y;
y++;
}
else
{
x=x-y;
y--;
}
}
2.)
#include <iostream>
using namespace std;
int main()
{
int x, y;
x=30;
y=20;
if(x<y)
{
x=x*3;
y=y*2;
}
else
{
x=x/3;
y=y/2;
}
}
3.)
#include <iostream>
using namespace std;
int main()
{
int x = 8;
int y = 3;
y = x - y;
if(x<2)
{
x--;
y--;
}
else if (x>=5)
{
x++;
y++;
}
else
{
x=200;
y=400;
}
}
4.)
#include <iostream>
using namespace std;
int main()
{
int x = 22;
int y = 20;
y = y-x;
x=x-y;
if(x<=20)
{
x = y-x;
y=y+x;
}
else
{
x = y+x;
y=y-x;
}
}
Explanation / Answer
// 1) c++ code
#include <iostream>
using namespace std;
int main()
{
int x, y;
x=10;
y=15;
if(x >= 9)
{
x=x+y;
y++;
}
else
{
x=x-y;
y--;
}
cout << "x: " << x << endl;
cout << "y: " << y << endl;
return 0;
}
/*
output:
x: 25
y: 16
*/
// 2) c++ code
#include <iostream>
using namespace std;
int main()
{
int x, y;
x=30;
y=20;
if(x<y)
{
x=x*3;
y=y*2;
}
else
{
x=x/3;
y=y/2;
}
cout << "x: " << x << endl;
cout << "y: " << y << endl;
return 0;
}
/*
output:
x: 10
y: 10
*/
// 3) c++ code
#include <iostream>
using namespace std;
int main()
{
int x = 8;
int y = 3;
y = x - y;
if(x<2)
{
x--;
y--;
}
else if (x>=5)
{
x++;
y++;
}
else
{
x=200;
y=400;
}
cout << "x: " << x << endl;
cout << "y: " << y << endl;
return 0;
}
/*
output:
x: 9
y: 6
*/
// 4) c++ code
#include <iostream>
using namespace std;
int main()
{
int x = 22;
int y = 20;
y = y-x;
x=x-y;
if(x<=20)
{
x = y-x;
y=y+x;
}
else
{
x = y+x;
y=y-x;
}
cout << "x: " << x << endl;
cout << "y: " << y << endl;
return 0;
}
/*
output:
x: 22
y: -24
*/
