Chapter 2

Write equivalent compound statements if possible. a. \(\quad x=2 * x\) b. \(x=x+y-2\) c. \(\quad\) sum \(=\) sum \(+\) num d. \(\quad z=z * x+2 * z\) e. \(y=y /(x+5)\)

Write the following compound statements as equivalent simple statements. a. \(\quad x+=5-z\) b. \(\quad y^{*}=2 * x+5-z\) c. \(\quad w+=2 * z+4\) d. \(x-z+y-t\) e. sum \(+=\) num

Suppose \(a, b,\) and \(c\) are int variables and \(a=5\) and \(b=6 .\) What value is assigned to each variable after each statement executes? If a variable is undefined at a particular statement, report UND (undefined). a = (b++) + 3; __ __ __ c = 2 * a + (++b); __ __ __ b = 2 * (++c) - (a++);

Suppose a, b, and sum are int variables and \(\mathrm{c}\) is a double variable. What value is assigned to each variable after each statement executes? Suppose \(a=3\) \(b=5,\) and \(c=14.1\) sum = a + b + c; ___ ___ ___ ___ c /= a; ___ ___ ___ ___ b += c - a; ___ ___ ___ ___ a *= 2 * b + c;
