For the function definition int SomeFunc ( / * in * / int alpha, / * in * / int beta) { int gamma; alpha = alpha + beta; gamma = 2 * alpha; return gamma; } what is the function postcondition?

A function post-condition refers to what will happen and return after calling the function.

Given the function definition as follows:

int SomeFunc ( / * in * / int alpha, / * in * / int beta) { int gamma; alpha = alpha + beta; gamma = 2 * alpha; return gamma; }

If we call the function by passing two values, 3 and 4, as input parameters, the 3 will be captured by alpha and 4 by beta. The two input values will by calculated based on the formula defined inside the function as follows:

alpha = 3 + 4 = 7

gamma = 2 * 7 = 14

At last the function will return 14.
