if statement c++ code example

Example 1: c++ if example

if (20 > 18) {
  cout << "20 is greater than 18";
}

Example 2: elseif c++

if( a == 10 ) {
      cout << "Value of a is 10" << endl;
   } else if( a == 20 ) {
      // if else if condition is true
      cout << "Value of a is 20" << endl;
   }

Example 3: if else program in c ++

if (condition) {
    // block of code if condition is true
}
else {
    // block of code if condition is false
}

Example 4: C++ if else

#include<iostream>
using namespace std;

int main()
{
    int grade;

    cin >> grade;

    if( grade >= 60 )
        cout << "You Pass!" << endl;
    else
        cout << "You Fail..." << endl;

    return 0;
}

Example 5: if else in C++

//1
if(condition) {
   statement(s);
}
else {
   statement(s);
}
//2
(condition) ? (true_statement) : (false_statement)

Example 6: if else program in c ++

// Program to check whether an integer is positive or negative
// This program considers 0 as a positive number

#include <iostream>
using namespace std;

int main() {
     int number;

    cout << "Enter an integer: ";
    cin >> number;
    if (number >= 0) {
        cout << "You entered a positive integer: " << number << endl;
    }
    else {
        cout << "You entered a negative integer: " << number << endl;
    }
    cout << "This line is always printed.";
    return 0;
}
