C++ beginner need help

[Java]

I need to write a program to find the sum and average of two numbers in C program the one that starts with header files like #include<stdio.h> and #include<conio.h> up till now i cannot write a program that works keep in mind i am a beginner

A program can be seen as a step by step appoach to do work

First user inputs numbers that are variables or data that must be stored in memory

google scanf

Next basic maths calculate the average from those variable

google "assigning variables"

Finally the result (another variable stored in memory) is displayed on the screen

google printf

Post your links here and I can explain them.

You should have a basic ability to use a C compiler. Practice compiling a "Hello World" project befor you start

Longtime I dont do C/C++


#include<stdio.h>
#include<conio.h>

float x = 5, y = 7, avg, sum;

void main()
{
sum = x + y;
avg = sum / 2;

cout<< "The results are: \n ";
cout<< sum;
cout<< avg;
}
You can accept the input from the user using scanf

OK let me try



//
// Java you can change the title how you see fit but i will use this one
// Program to calculate the average of two numbers
// Average = sum / 2
//
#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;

int main(int nNumberofArgs, char* pszArgs[])
{
// enter First Number
int numbera;
cout << "Enter First Number:";
cin >> numbera;

// enter Second Number
int numberb;
cout << "Enter Second Number:";
cin >> numberb;

// use formula to calculate sum of numbera and numberb
int sum;
sum = numbera + numberb;

// use formula to calculate average of numbera and numberb
int average;
average = sum / 2

// output the results (followed by a NewLine)
cout << "The Average Of The Numbers Are:";
cout << average << endl;

// wait until user is ready before terminating program
system("PAUSE")
return 0;
}


That should do it i haven't tried compiling it as yet but if you are using the right compiler you should be able to see any errors so edit as you wish

AND KEEP IN MIND THAT I DID THIS OFF THE TOP OF MY HEAD so it will not be perfect

PS copy it into your compiler make sure nothing is in the same line as the { well u should know why

[Utech22]

That looks complicated for a noob.

[malco1987]

i actually thought yours was more difficult thats why i posted mine

PS: Java if you told me that any one of the variables would have a decimal then i would have to change the code

[Mixmasterxp]

a so unno just write out the man/woman homework star. a just straight copy and paste and loose marks that ya now.

Why did you need to use conio?

[malco1987]

No actually if he is true to himself he would never just copy and paste he would try to understand it fully first

Plus i posted it for him to make it his own, so to speak

the best place to start is by posting what you already did. Makes no sense us trying to teach you individual coding styles when you will need to develop your own.

[malco1987]

So java you not even come drop a link or nothing, let us know what's going on

[Java]

include <stdio.h>
include<conio.h>
void main ()
}
int num1,num2,sum;
sum=num1+num2;
printf("enter the first number/n");
scanf("%d",&num1);
printf("enter second number/n");
scanf("%d",&num2);
printf("the sum is, sum");
getch();
}

[Utech22]

I dont have a s/w to test it but:

printf("the sum is, sum"); should be
printf("the sum is %d", sum);

I'll have to check it out still. do you see the error above?

Fixed .

1st of all u r mixin c++ with c libraries which is wrong, if u r using c u use stdio.h if u use c++ u use iostream. This is C code below

#include <stdio.h>
#include <conio.h>

void main (void)
{
int n = 0, m = 0;
float total = 0.00;
scanf("%d", &m);
scanf("%d", &n);
total = n+m;
printf("%d",total/2);
getch();
}
