Solution

Here is the solution for problem a.

function main()
{
var score;
var total = 0;
for(i = 0; i < 5; i++)
{
score = getScore(score);
total = computeTotal(total, score);
}
console.log(\"The total of all the exams is \" + total);
}
function getScore (score)
{
score = Number(prompt(\"Enter your exam score\"));
return score;
}
function computeTotal (total, score)
{
total = total + score;
return total;
}
main();

The variable total should be initialized to 0, unless otherwise, it will contain a garbage value.

The solution for problem b:

function main()
{
var num;
var endProgram = \'y\';

while (endProgram == \'y\')
{
num = Number(prompt(\"Enter a number to be squared\"));
num = num * num;
console.log(\"Your number squared is \" + num);

endProgram = prompt(\"Enter y to square another number\");
}
}
main();
