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")

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;

}

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;
}

#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.
