a. num1 = 35;

Explanation of Solution

num1 = 35; is a valid assignment as integer 35 is be...

Explanation of Solution

newNum = num1 – num2; is a valid assignment although the variables num1 and num2 have not been initialized. If a variable is used in an expression, the expression would yield a meaningf...

c. num1 = 5; num2 = 2 + num1; num1 = num2 / 3;

Explanation of Solution

num1 = 5; num2 = 2 + num1; num1 = num2 / 3; are valid assignments. num1 =5; declares and initializes the variable num1. num2 = 2 + num1; assigns the value of the expression 2 + num1 to num2. Since num1 has been declared and assigned a value, the right-hand expression value is 2 + 5 = 7...

d. num1 * num2 = newNum;

Explanation of Solution

num1 * num2 = newNum; is not a valid assignment as the left hand of a valid assignment is a variable and not an expression...

e. x = 12 * num1 - 15.3;

Explanation of Solution

x = 12 * num1 - 15.3; is a valid assignment although the variable num1 in the expression on the right-hand side has been declared but not initialized before being used in the expression. If a variable is used in an expression, the expression would yield a meaningful value only if the variable has first been initialized...

Explanation of Solution

num1 * 2 = newNum + num2; is not a valid assignment as the left hand of a valid assignment is a variable and not an expression...

Explanation of Solution

x / y = x * y; is not a valid assignment as the left hand of a valid assignment is a variable and not an expression...

x = x + y - 5; is a valid assignment although the variables x and y have not been initialized before being used in the expression. The expression on the right side...

k. newNum = num1 + static_cast<int> (4.6 / 2);

Explanation of Solution

newNum = num1 + static_cast<int> (4.6 / 2); is a valid assignment. The expression on the right-hand side evaluates an unpredictable but int type value. The expression inside the parentheses is evaluated first where the denominator is implicitly casted to floating-point type (as the numerator is floating-point type)...

Given a structure for student as follows: struct student { int ID; float grade; } s[5]; Use scanf to have user enter ID and grades for each student: 1st student ID =1, Grade = 90 2nd student ID=2, Grade = 81.5 3rd student ID=3, Grade = 85.5 4th student ID=4, Grade = 88 5th student ID=5, Grade = 94 Each student as a structure needs to have the ID and grade properly set. Output: The average grade for 5 students' needs to be reported using printf. Also, each student ID and Grade need to be reported. NOTE: Use structure syntax as needed. Use for loop when you deal with arrays.
