Question
Study the following program:main() { int a = 1, b = 2, c = 3: printf("%d", a + = (a + = 3, 5, a)) } What will be the output of this program? (A) 6(B) 9(C) 12(D) 8
Solution
The program you provided seems to be written in C, but it contains a syntax error. The colon after the variable declaration should be a semicolon. Also, the use of the comma operator in the expression a += (a += 3, 5, a) is not correct.
In C, the comma operator evaluates its left operand and discards the result, and then evaluates the right operand and returns this value. So, (a += 3, 5, a) would return the value of a, not 5.
However, the += operator is an assignment operator that adds the value of the right operand to a variable and assigns the result to the variable. The use of += in this context is not correct.
Therefore, the program as it stands would not compile, and it's not possible to determine what the output would be.
Please check the program and try again.
