Hi All, I have just started Learning C programming at college and I''m quite stuck with a basic excercise we''ve been asked to complete, this is basically what we have to do. "Write a program to input your name, height in inches and weight in pounds, convert the height to centimeters and weight to kilograms and display the followoing results." 1 inch = 2.54 cm and 1 pound = 0.4546kg. Now I know this is extremely basic to most peeps on here but i''d appreciate if someone could give me a few tips on how I should set this out and what syntax to use cause im just going round in circles. Thanks alot Kiwi Fella

Since it''s C, use scanf() to read the variables.

Use a=b*c; to convert the values to different system.

Use printf(); to display the results.

And go to
http://msdn.microsoft.com/
to read more about scanf and printf.

Remember to initialize your variables before using them.

Thanks civguy,

I know about printf and scanf and also we have learnt about If,Else statements, the basics you know? but im unsure of how I go about setting this programme out, this is how im setting it out

#include <stdio.h>

int main()
{
char = height,weight,centimeters,kilograms,pounds;

Am I on the right track doing this?, if someone could fill in the gaps in in this so I can get an idea of how to set it out I''d appreciate it alot, Thanks again

char = height,weight,centimeters,kilograms,pounds;
int = a,b,c

Height, weight etc. aren''t characters. They are real numbers. Also, the = is wrong. Don''t you have a book where to learn these basics?

  
double height,weight,centimeters,kilograms,pounds;
int a,b,c;

Bro when I mean basic sh*t we''ve learnt I mean basic, I understand what some of the syntax means but actually applying it is another story, I just need someone to set this out so I can get an idea.

ok...i'll make this easy for you...
i'm not gonna do your homework for you though.

    
void main()
{
//init. varibles...i would go with 2 ints (iHeight, and iWeight) and a char (cName)

//please excuse the psydo-Hungarian notation


//Get the user input


printf("Hi, i'm Mr. Computer, whats your name? ");
scanf("%s",&cName); //check this, it's been awhile since i used

                   //scanf...

//etc....


//change the weight around

iWeight /*pounds*/ = iWeight*0.4546; //iWeight is now KG's


//spit it all back out

printf("Ok, %n weighs %i killograms and is %i meters tall\n",cName,iWeight,iHeight); 

}

thats how i would do it..

edit: i messed up the code just a bit...
