Really need HELP with these!

1. The user is required to enter a number that is not between 1 and 5 (ie 1, 2, 3, 4, and 5 are not allowed) If they enter an invalid number, print an error message, otherwise do nothing. Note: Use an if statement with a compound condition.

2.Given a program designed to accept input from command line with the following first line to the main program and command issued on command line, answer the following questions: Command line input: a.out 15 25 First line of main program: int main(int argc, char *argv[]) { a. What variable represents the number of items on command line? b. What is the value of argc? c. Where is the 15 entered on command line stored? d. Where is the 25 entered on command line stored? e. Write a line of code that would take the second item entered on command line (15) and assign it to an integer variable named num1.

3. count = 3; sum = 0; while (count > 1) { sum = sum + count; count = count 1; }

printf (Sum is %d , sum); printf(Count is %d , count);

a.) num = 0; while (num < 5)

printf(%d , num); num = num + 2; b.) for (j = 7; j < 0; j--) printf(%d , j)
