Write a C++ program to declare two integers and one float variables; assign 10, 15 and 12.6 to them respectively. Print the values on the screen.
#include<iostream>
using namespace std;
int main()
{
int x=10;
int y=15;
float z=12.6;
cout<<"The value of x is "<<x<<endl;
cout<<"The value of y is "<<y<<endl;
cout<<"The value of z is "<<z<<endl;
return 0;
}
Write a C++ program to prompt the user to input 3 integer values and print these values in forward and reversed order, as shown below.
Please enter your 3 numbers: 12 45 78 Your numbers forward: 12, 45, 78. Your numbers reversed: 78, 45, 12.
#include<iostream>
using namespace std;
int main()
{
int x,y,z;
cout<<"Please give the fist number "<<endl;
cin>>x;
cout<<"Please give the second number "<<endl;
cin>>y;
cout<<"Please give the third number "<<endl;
cin>>z;
cout<<"Print the values in forward order "<<x<<", "<<y<<", "<<z<<"."<<endl;
cout<<"Print the values in reversed order "<<z<<", "<<y<<", "<<x<<"."<<endl;
return 0;
}
Write a C++ program to declare 3 variables of type int. Assign the values 10 and 15 to the first two of the variables and assign their product to the third variable. Print on the screen the 3 values.
#include<iostream>
using namespace std;
int main()
{
int x,y,z;
x=10;
y=15;
z=x+y;
cout<<"The sum of "<<x<<" and "<<y<<" is "<<z;
return 0;
}
Write a C++ program to compute the maximum of two real numbers.
#include<iostream>
using namespace std;
int main()
{
int a,b,max;
a=10;
b=15;
if (a>=b) max=a;
else max=b;
cout<<"The maximum of "<<a<<" and "<<b<<" is "<<max;
return 0;
}
Write a C++ program to compute the absolute value of a real number.
#include<iostream>
using namespace std;
int main()
{
int a, absolute_value;
a=-10;
if (a>=0) absolute_value=a;
else absolute_value=-a;
cout<<"The absolute value of "<<a<<" is "<<absolute_value<<endl;
return 0;
}
