How do I use nested if-else statements in C++?
Nested if-else statements allow you to check multiple conditions in C++. You can place an if-else statement inside another if or else block.
Can you give me an example?
Sure! Here's a simple example:
int x = 10;
if (x > 0) {
if (x < 20) {
std::cout << "x is between 0 and 20";
} else {
std::cout << "x is 20 or more";
}
} else {
std::cout << "x is 0 or negative";
}
What happens if I don't use the else part?
If you don't use the else part, the program will simply skip the block if the condition is false, and no action will be taken.
