The run command window is a fast and efficient way to directly access Windows' functions, without sifting through the Control Panel or other menus. I have summarized a comprehensive list of run commands that are tested in Windows 7, 8, and 10. The commands are not case-insensitive. Open the Run command window (press the windows Key + R). Afterward, type any of the following commands and click OK or press Enter. That’s it!

Problem: A Simple Program To Find The Absolute Value Of An Integer. Method 1:  #include <iostream> using namespace std; int main() { int number; int abs_number; cout << "Enter an integer (positive or negative): " << endl; cin >> number; // Find the absolute value if(number >= 0) { abs_number = number; } else abs_number = -number; // Print out output cout << "The absolute value of " << number << " is " << abs_number; cout << endl; return 0; } Output: Enter an integer (positive or negative): -11 The absolute value of -11 is 11

if statement: #include <iostream> using namespace std; int main()  { int a, b; cout << "Enter first number: " << endl; cin >> a; cout << "Enter second number: " << endl; cin >> b; if(a < b) cout << "First number is less than second.\n"; return 0; } Output: Enter first number: 5 Enter second number: 7 First number is less than second. if-else statement: #include <iostream> using namespace std; int main()  { int a, b; cout << "Enter first number: " << endl; cin >> a; cout << "Enter second number: " << endl; cin >> b;
