How to get started C Programming Language Study?

C Programming Language study is simple, humble and at the same time complicated, too. First we have to check whether C Programming setup file installed or not in our Computer. Perhaps it may be installed or it can even be copied from other Computer. If it is copied, the folder named TC must be in the same DRIVE as in the source Computer, otherwise it will not work properly and will get an error like "stdio.h can't open", because the source and destinations drives are different. Then find the file named "TC.EXE" in the computer and double click on that, then we will get the C Programming interface, ie a window will appear, there we can open new file and write C Programe. After the completion of the programe, just save file as "anyname.c" and then this file has to be Compiled using the keys "Alt+F9" and, if there is no error seen, Run using the keys "Ctrl+F9" then output will be displayed in the Monitor.

C Program to find Prime Number using UDF, also find Prime Numbers upto a limit in C Language

C Program to find Prime Number using UDF, also find Prime Numbers upto a limit in C Language: Example 1 : C Program to find prime number using user defined function :- #include<stdio.h> #include<conio.h> int primeNumber(int); /* function declaration or prototype, int arg int returns */ void main() { int num,prime; clrscr(); printf("Enter an integer Number :"); scanf("%d",&num); prime = primeNumber(num); /* function call here with Actual Parameter num, rtns integer value and assigning to the var prime */ if(prime==1) printf("%d is a prime number",num); else printf("%d is not a prime number",num); getch(); } int primeNumber(int n) /* function definition with Formal Parameter n and returns an integer */ { int i; for( i=2 ; i<=n/2 ; i++) { if(n%i==0) return 0; } return 1; } /* prime number 3,7,11,17.... */ Example 2 : C Program to find prime num...
