跟踪 if 语句被使用 true 的次数

Question

我认为这个问题本身就说明了问题，我正在用 C++ 编写一个程序，其中有一部分控制台询问用户他们想要使用哪种类型的输入，

while (loop == 5) {
  cout << "\nWould you like to enter a depoist or a check? "; //asks for a choice
  cin >> choice;
  //determines whether or not to close the program
  if(choice == 0 || depo == 0 || check == 0) {
    return 0;          
  }//end close if
  //choses which type of input to make
  if( choice == 1) {
    cout << "\nPlease enter check amount: ";    
    cin >> check;
    check += check;
  } else if(choice == 2) {
    cout << "\nPlease enter deposit amount: ";
    cin >> depo;
    depo += depo;
  }//end if
}

但是我如何跟踪 if 语句为 true 的次数？

Answer 1

您可以添加一个计数器，并在每次进入 if 语句的 true 块时递增它。

int true_counts = 0;
while (loop == 5){

    ...

    if( choice == 1){
        true_counts++;

    ...
