    Well a printf/scanf of the input procedure would be a start.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    > I just don't know how to imput them.
    Code:
    double v, u = 10, a = 9.8, t = 5;
    v = u + a*t;
    It's that simple.

    Code:
    #nclude <stdio.h>
    int
    main()
    {
    	printf("");
    	return 0;
    }

    How on earth did you manage problem #1?

    I mean, surely you could manage
    Code:
    printf("Enter launch speed (ft/s): ");
    scanf("%f",&lunchSpeed);  // I'll leave you to declare a suitable variable

    Problem 1 was just executing a program that pops up with a message "i'm the best programmer"

    Code:
    #include <stdio.h>
    int
    main()
    {
    	printf("Enter launch speed (ft/s): ");
    	scanf("%f", &launchSpeed); 130.5
    	return 0;
    }
    Its giving me syntax errors, I put the variable in the right place right?

    Because 130.5 is something you type into the running program, not the source code.

    And declare your variables.

    would declaring a variable be some like x=launch speed? in the line you said? or something like int?
