Evaluate Formulae

Given four integer variables a, b, c, and d, write a single expression to evaluate the following formula:

\frac{a + b}{c} + d

Use integer division while evaluating the expression.

Examples:

Input: a = 10, b = 4, c = 7, d = 9
Output: 11
Explanation: 10 + 4 = 14, 14 / 7 = 2 and 2 + 9 = 11.

Input: a = 5, b = 6, c = 8, d = 9
Output: 10
Explanation: 5 + 6 = 11, 11 / 8 = 1(integer division) and 1 + 9 = 10.

The key idea is very simple: directly translate the given mathematical formula into a programming expression.

Since all inputs are integers and integer division is required, the division operation should be performed using integer operands so that the fractional part is discarded.

• Read the four integer values a, b, c, and d.
• Substitute these values into the given formula.
• Use the corresponding arithmetic operators to construct the expression.
• Perform the division using integer arithmetic and print the resulting value.

int main()
{
    int a, b, c, d;
    // cin >> a >> b >> c >> d;
    a = 10;
    b = 4;
    c = 7;
    d = 9;

    // Calculate the expression using integer division.
    int res = ((a + b) / c) + d;

    cout << res << endl;

    return 0;
}

    int a = 10;
    int b = 4;
    int c = 7;
    int d = 9;

    int res = ((a + b) / c) + d;

    printf("%d\n", res);
