C pointer principle (71)-C Quick Start (5)

(5) repeatedly accept player input, only until the number is guessed

The C program uses the else if statement block to implement a set of conditional statement blocks with multiple different conditional statements. Its usage is shown as follows:

If (condition 1 ){

.........

}

Else if (condition 2 ){

..........

}

Else if (Condition 3 ){

.........

}

......

......

Else if (condition n ){

.........

}

Else {

.........

}
