The program segment has errors. Find as many as you can.
// This code should average a set of numbers. int numCount, total;double average;
cout << "How many numbers do you want to average? "; cin >> numCount;for (int count = 0; count < numCount; count++)
{int num;cout << "Enter a number: "; cin >> num;total += num; count++;}average = total / numCount;cout << "The average is << average << end1;
The program segment has errors. Find as many as you can.
// This code should display the sum of the numbers 1 - 100. int count = 1, total;
while (count <= 100) total += count;
cout << "The sum of the numbers 1 - 100 is ";
cout << total << end1;
1.Convert the while loop in the following program to for loop.
#include
int main()
{
Int num rem,reverse_num3%3;
printf("nEnter any number:");
scanf("%d",&num);
while(num>=1)
{
rem=num%10;
reverse_num=reverse num*10+rem;
num=num/10;
printf(nReverse of input number is:%d",reverse_num);
return 0:

Valid test score entries are between 0 and 100 inclusive. The program should display a welcome message and run everything through the "main" function. have the ability to enter several test scores (try a loop) and print out the total score, as well as, the average score. continuously ask for test scores until the number 99.9 has been entered. test for valid entries and the value 99.9. If a test score is valid, the program should add the current score to the total score and update the number of test scores by one (+1), otherwise it displays an error message.
