program in C

6. (5 pts) Write an expression that evaluates to 1 if a is the largest among integers a, b, and c and to 0 otherwise. If you used any parentheses, you must tell whether each pair of parentheses is redundant. 7. (5 pts) Write an expression that evaluates to O if x is between 20 and 100, inclusive, and 1 otherwise. 8. (10 pts) Give the output of the following program fragment. Explain how alpha is computed to the value you give. int alpha = 11, beta = 5, gamma = 4; alpha /= beta++ - --gamma; printf("%d %d %d ", alpha, beta, gamma); 9. (10 pts) Give the values of x and y after the following statements are executed. Provide a fully detailed explanation about how you arrive at such values, including all the binary forms. int x = 18; x = x >> 3; int y = 12; y = y
