In C++, we can use comparison operators to compare two numbers. The comparison operators in C++ are < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to), == (equal to) and != (not equal to).
Here are some examples of how to use these comparison operators:
``c++
#include
using namespace std;
int main() {
int a = 10, b = 5;
// using < operator to check if a is less than b
if(a < b) {
cout << "a is less than b" << endl;
} else {
cout << "a is not less than b" << endl;
}
// using > operator to check if a is greater than b
if(a > b) {
cout << "a is greater than b" << endl;
} else {
cout << "a is not greater than b" << endl;
}
//using <= operator to check if a is less than or equal to b
if(a <= b) {
cout << "a is less than or equal to b" << endl;
} else {
cout << "a is not less than or equal to b" << endl;
}
//using >= operator to check if a is greater than or equal to b
if(a >= b) {
cout << "a is greater than or equal to b" << endl;
} else {
cout << "a is not greater than or equal to b" << endl;
}
//using == operator to check if a is equal to b
if(a == b) {
cout << "a is equal to b" << endl;
} else {
cout << "a is not equal to b" << endl;
}
//using != operator to check if a is not equal to b
if(a != b) {
cout << "a is not equal to b" << endl;
} else {
cout << "a is equal to b" << endl;
}
return 0;
}
Output:
a is not less than b
a is greater than b
a is not less than or equal to b
a is greater than or equal to b
a is not equal to b
a is not equal to b
