Read int and char array from keyboard
#include <iostream>
#include <stdio.h>
using namespace std;
main(void)
{
int i;
char str[80];
cout << "I like Turbo C++.\n";
printf("You can use printf(), but most C++ programs don"t.\n");
cout << "enter a number: ";
cin >> i;
cout << "your number is " << i << "\n";
cout << "enter a string: ";
cin >> str;
cout << str;
return 0;
}Read int and do the calculation
#include <iostream>
using namespace std;
int main()
{
cout << "How many pennies do you have? ";
int count;
cin >> count;
double total = count * 0.01;
cout << "How many nickels do you have? ";
cin >> count;
total = count * 0.05 + total;
cout << "How many dimes do you have? ";
cin >> count;
total = count * 0.10 + total;
cout << "How many quarters do you have? ";
cin >> count;
total = count * 0.25 + total;
cout << "Total value = " << total << "\n";
return 0;
}Read integer from console using cin
#include <iostream>
using namespace std;
int main()
{
int length;
int width;
cout << "Enter the length: ";
cin >> length; // input the length
cout << "Enter the width: ";
cin >> width; // input the width
cout << "The area is ";
cout << length * width;
return 0;
}Enter the length: 12
Enter the width: 12
The area is 144"
Use relational operators to compare int type variables
#include <iostream>
using namespace std;
int main(){
int numb;
cout << "Enter a number: ";
cin >> numb;
cout << "numb<10 is " << (numb < 10) << endl;
cout << "numb>10 is " << (numb > 10) << endl;
cout << "numb==10 is " << (numb == 10) << endl;
return 0;
}
