Stuck in these two similar programs

ReitaBassist · #1 30-Mar-2009, 14:12

This is what I've already done:

CPP / C++ / C Code:

#include <stdio.h>
#include "simpio.h"
#include "genlib.h"
main()
{
int base, power, mul;
printf("Enter the base");
base=GetInteger();
printf("Enter the power");
power=GetInteger();
while(base!=0)
{

Objective is to write a program that calculates the power of a number by using the multiplication sign.

Stuck with the same part of the next one:

CPP / C++ / C Code:

#include <stdio.h>
#include "simpio.h"
#include "genlib.h"

main()
{
      int num, max, min;
      
      printf("Signal the end of your list with 0.\n");
      max=0; min=0;
      printf("Enter first number");
      num=GetInteger();
      while(num!=0)
      {

Objective: write a program that finds the maximum and minimum number of a list.

I just got a little stuck with what should go after the "{". Any help?

Why don't we take them one at a time? Get the first one under your belt, and maybe you will gain some insight that will help with the second one (and the many, many programs to follow).

I would formulate the problem as follows:

Code:


Declare integer variables for base, power and result.

Get the "base"  integer from the user. (Make sure it is positive.)
Get the "power" integer from the user. (Make sure it is not negative.)

Set "result" equal to 1

Peform the following "power" times:
    result = result * base

Note that a useful idiom (and probably the most used construct) in C and C++ if you want to do something n times is

CPP / C++ / C Code:

    int i;
    for (i = 0; i < n; i++) {
        /* Do something */
    }

I mean, there are other looping constructs, but if I know how many times I want to do something, I (usually) just use a "for" loop to count the iterations.

Regards,

Dave
