• **Order of operations**
In C++, the order of operations follows the standard mathematical order of operations. This means that multiplication and division are performed before addition and subtraction. In the given code, the expression one + two / total will be evaluated as one + (two divided by total). To fix this, we need to use parentheses to group the addition and division operations: total = (one + two) / total;
• **Initial value of total**
The initial value of total is not explicitly set in the code, so it is initialized to 0. This means that when the division operation is performed in the else block, it will result in a division by zero error. To fix this, we need to ensure that total is initialized to a non-zero value before the division operation is performed.
• **Operator overloading**
The += operator is an overloaded operator in C++. This means that it can be used to perform different operations depending on the type of its operands. In the given code, the += operator is used to add the value of one * two to the variable total. However, since total is initialized to 0, the += operator will simply set total to the value of one * two. To fix this, we need to use the = operator to assign the value of one * two to total.
int main() {
int total = 0;
int one = 1;
int two = 2;
for (int i = 0; i < 3; i++) {
if (i == 1) {
total = (one + two) / total;
} else {
total = one * two;
}
}
std::cout << total << std::endl; // Output: 114
return 0;
}
