I am not familiar with Ubuntu. I checked online for some C compilers (It doesn't really matter to me if I am compiling in .exe or .deb as long as I can study) but I couldn't find any in the style I am familiar with. As far as the terminal goes, I don't even know how to do that. I want to learn more about programming in Unix based operating system but I am used to windows. The source doesn't matter because it's not the source that is listed on the errors, it's using dev-c++ debug. But debug is the only way I seem able to get it to display, But here is the source of that one program: ....... /* Filename: C7DIV.C Displays user's weekly pay */ #include <stdio.h> main() { float weekly, yearly; printf("What is your annual pay? "); // Prompt user scanf("%f", &yearly); weekly = yearly/52; // Computes the weekly printf("\n\nYour weekly pay is $%.2f", weekly); #include "CLOSE.C" return 0; } ....... And here is the source for CLOSE.C (I came up with this to help me follow along better with books.) printf(" \n"); printf(" \n"); printf(" \n"); printf("_________________________________\n\n"); printf("End Of Program.\n\n"); printf("To close, type any key and press enter. "); scanf(" ");
