    :)Hello guys,
    i have a c++ homework and iam facing some problems, so if anyone can help me with these question i'll appreciate it.
    regards,
    Emad:)
    These are the questions:
    1- Write a program that reads
    five numbers (each between 1 and 30). For each number read, your
    program should print a line containing that number of adjacent asterisks.
    For example, if your program reads the number seven, it should print
    *******.
    Your screen should appear as follows:
    Enter 5 numbers between 1 and 30: 5 12 8 6 11
    *****
    ************
    ********
    ******
    ***********

    2- The factorial function is used frequently in probability
    problems. The factorial of a positive integer n (written n! and pronounced ''n
    factorial'') is equal to the product of the positive integers from 1 to n. Write
    a program that evaluates the factorials of the integers from 1 to 5. Print the
    results in tabular format. What difficulty might prevent you from calculating
    the factorial of 20? Your screen should appear as follows:
    x Factorial of x
    1 1
    2 2
    3 6
    4 24
    5 120

    Have you studied loops yet? because the first one is fairly trivial and can be done in just about 4 or 5 lines of codes. I suggest you start here:
    cplusplus.com/doc/tutorial/control/

    sorry for the badly formated link, but when I tried to send the post for some reasons the system flags my post as spam :(

    Hey man here is the complete solution
    Don't worry ask your questions here but next time do homework yourself if you are interested in programming



    Code:
    #include<conio.h>
    #include<stdio.h>
    void main()
    {int a,b,c;
    clrscr(); for(c=1;c<=5;c++) {
    printf("\nEnter the number between 1 and 30 \n");
    scanf("%d",&b);
    if(b>1&&b<30)
    {
    for(a=1;a<=b;a++) { printf("*"); }printf("\n");
    }else
    printf("Entered number is out of range\n");
    }getch(); }
