Add two integers

Challenge

Write your first C function: take two integers and return their sum.

Task

Implement int add(int a, int b) that returns a + b. No main — the grader calls your function.

Input

Two ints a and b.

Output

Returns their sum, as an int.

Example

add(2, 3)    ->   5
add(-4, 1)   ->   -3
add(0, 0)    ->   0

Edge cases

• Negative operands work the same way.

Input format

Two ints a and b.

Output format

Their sum, as an int.

Constraints

a and b are signed 32-bit integers whose sum fits in a standard int.

Starter code

int add(int a, int b) {
    /* TODO */
    return 0;
}

Common mistakes

Printing the result with printf rather than returning it from the function.

Edge cases to handle

Zeros, negative operands, additive inverses yielding zero.
