2. Prog Assignment Question Two.txt

/*Qn2
Code by Nsubuga Richard, 17/U/20353/PSA, BELE
a) Write a header for a function named do_it( ) that takes
   three type char arguments and returns  type float to the calling program.
   Solution
   float do_it(char char1,char char2,char char3)//This is the header for the function do_it

b) Write a header for a function named printf_a_number ( ) that takes
   a single type int argument and doesn’t return anything to the calling program.
   Solution
   void printf_a_number(int num)//This is the header for the function printf_a_number

c) What’s wrong with the following program?
    #include <stdio.h>
    void print_msg(void);
    main( ){
    print_msg("this is a message to print");
    return 0;
    }
    void print_msq(void)
    {
    puts("This is a message to print");
    return 0;
    }
    */
//the correct program is as below
#include <stdio.h>
    void print_msg(void);
    main( ){
    print_msg();
    return 0;
    }
    void print_msg(void)
    {
    puts("This is a message to print");
    return 0;
    }
/*Corrected errors
1. The function prototype has no formal argument/parameter but
the function call is having an Actual argument so the program
cannot proceed to call the function.
2. The function declaration and the function header were
using different function names, declaration was using
"printf_msg" and header was using printf_msq*/
