How do I set variables?

[plutoniumman]

Hello, I have been trying to set variables for a long time and I can't figer it out!
So If you know how to set variables in C, PLEASE POST IT HERE!

[Jason]

int c;


for vars to be set in C they need to be declared at the begining of the method or main functions...

umm.... ok.
do you know how to do this in C:

<script>
<!--
var TEST = prompt ("Type some thing","")
TEST2=10
if (TEST2 == "10" || TEST == "20"){
document.write("Hello")
} else {
document.write("hi")
}
//-->
</script>

Can you do this in C?
My book leaves out brackets in there syntax so I get a lot of errors when I try stuff.

This is how you display words right?

printf("words are in here")

[Jason]

var TEST = prompt ("Type some thing","")
TEST2=10
if (TEST2 == "10" || TEST == "20"){
document.write("Hello")
} else {
document.write("hi")
}

#include <stdio.h>

int main () {
char TEST [20]= "type something";
int TEST2 = 10;

if ( TEST2 == 10 || TEST2 == 20 ){
    printf("%s","Hello");
}
else {
    printf("%s","hi");
}

return 0;

}

the code doesnt prompt me to set the variable TEST.
Thank you for your help!

You have to use printf to print the prompt, and then scanf to get the value:

#include <stdio.h>

int main () {
  char text[20];
  printf("Enter a string:\n");
  scanf("%s",text);
  printf("You entered : %s.\n",text);
  return 0;
}

[Jason]

#include <stdio.h>



int main () {

char TEST [20];

int TEST2 = 10;

   //shmooves coded added here....
  printf("Type Something\n");
  scanf("%s",TEST);
  printf("You entered : %s.\n", TEST);

if ( TEST2 == 10 || TEST == "20" ){

    printf("%s","Hello");

}

else {

    printf("%s","hi");

}



return 0;



} 

Next time try some code yourself, this was fairly simplistic...

I have three compilers, Bloodshed, HAM, and one from Barland.
HAM has some sample code, I have been trying to chang it the way I want it for about a 5 months and nothing happins.

Thank you for your help, I'm just going to get all the books on C at the library I can find.

The code Jason has posted gets some where!
I will take it apart and see how He did it.
