cout << "Looks like you just have enough" << endl;
cout << "The amount of cash back will be " << (sum - cost) << endl;

//The goal of the program is to put in a certain amount of money a person has, then it subtracts the total amount that a product costs. the program will respond with a total amount of money as well as something to say about being able to buy more products or not, it will then ask for a second item and its cost then find the sum of that and so on
The problem is that I cant finish the if and else statement, and the program doesnt loop to ask if there are anymore products, and the program only runs if i have the if statements written above in the certain order.
Also this is what outputs when i put in the cash of 10 and the cost of 9:
How much money do you have? 10
How much does this product cost? 9
Looks like you'll have enough money to pay for the product
The amount of cash back will be 1
Looks like you just have enough
The amount of cash back will be -8
Looks like you'll need more money to buy the product
The amount of money needed to buy the product is -1
for(loopCount = 0; loopCount < Yourchoicehere; loopCount++)
{
//Stuff you want to loop through
}
Youchoicehere could be a number to loop to, or you can use user input as well to end it.
Next you need to use brackets with if statements, what is in between the brackets.
1 2 3 4 5 6 7 8 9
if (cash == cost)
{
cout << "Looks like you just have enough" << endl;
cout << "The amount of cash back will be " << (sum - cost) << endl;
}
elseif (condition)
{
// Code
}
if, else, and loop statements stop at the first semicolon or after the following braces.
Newlines/indentation/whitespace is irrelevent
Examples:
1 2 3 4 5 6 7 8 9 10 11 12 13
if( some_condition )
PartOfIfStatement(); // <- semicolon, if stops here
NotPartOfIfStatement();
//...
if( some_condition )
{ // <- opening brace
PartOfIfStatement();
AlsoPartOfIfStatement();
} // <- closing brace, if stops here
NotPartOfIfStatement();
Your problem is you have a semicolon immediately after the if, effectively making it worthless:
1 2 3
if (cash < cost); // <- semicolon, if stops here (ie: does nothing)
cout << "Looks like you'll need more money to buy the product" << endl; // <- not part of if statement
