Here is my problem..... I have to do a few programs/labs. Just simple shell programs but I can only do them on campus using Linux.


So my question is ...is there a program to simluate unix...

okay...i think i got it figured out now

thanks

thats the problem..i could not find the GCC file itself or BIN directory

but i'll try Dev-C++

okay...for example when using JDK when you compile java files...you go to JDK/BIN/
and there you use javac to compile


I'm not sure how this works with GCC

i have the folder itself

when I...

i need to run the following commands...

gcc file1.c -o file1
gcc file2.c -o file2
/file1
/file2


how do i do that?

I need some help with GCC compiler. I downloaded and extracted the files. After that I'm not really sure what to do.


I need to use GCC to run C applications

How do i install or use gcc compiler on my computer?

THanks

never mind...got it working

I'm confused :confused:

I have to creat 2 matrices and then produce a third matrxi. But here is the problem that i have:

Question states "third matrix whose all off diagonal entries are zero...

yeah baby i fixed it


changed OUTPUT(poutput); to

OUTPUT(psum);

i guess that make sense.....although now i dont get float values

#include <stdio.h>

void INPUT(int *var1, int *var2, int *var3, int *var4);
void AVERAGE(int var1, int var2, int var3, int var4,float *var5);
void OUTPUT(float *var);

main(){

int x,y,z,v;...

I have this program that asks you to input numbers, takes the average and prints it out.... its pretty easy if you do by Value but i have to do it using Call by reference....so far i have :


...

thanks..that worked. :D

#include <stdio.h>


float AVERAGE(int num1, int num2, int num3, int num4);
float OUTPUT(float output);

int main(void){

int a,b,c,d,x, avr, out;

nope..that did not help

I have this simple program...that takes 4 integers and prints out the average




#include <stdio.h>


int AVERAGE(int num1, int num2, int num3, int num4);
float OUTPUT(float output);

okay...it works now.

I just need to work on the logical part now.....it does not work as it should.

okay...here is my first try:





#include <stdio.h>


int main(void){
