将转换为大写选择配置余额

if (configureMenuChoice == 'A') { 
    CLS; 
    printf("How much would you like to add to your account balance? \n");

这直接增加了平衡

scanf("%i", &deposit); 
    *balance = *balance + *deposit; 
} 
if (configureMenuChoice == 'C') { 
    CLS; 
    currentBalance(*balance);      // displays current balance, made a functino so it can be used at will 
} 
}//end conFigureBalance 

void currentBalance(int *balance) { 

printf("Your current balance is: %i\n", &balance); 

}//end checkBalance

@Deonte Threatt应该有scanf（“％i”，存款）;而不是scanf（“％i”，＆deposit）;在函数中。 –

更改此：

scanf("%i", &deposit);

这样：

scanf("%i", deposit);

因为deposit是在这种背景下（函数configureBalance的主体）int*类型。

这跟以下的逻辑相同：scanf("%c", userChoice);，所以我想知道你是如何错过它的。

我改变了这一点，但它的价值，当我添加存款的余额。 –
