Syntax of function in c

Function is block of program. When any program is very long then we try to cut the program in different parts( or blocks) so that whole program is more understandable and easier to debug (error checking).This part of program is called function. It is also useful when set of program uses many times in the program then instead of writing whole program in many time we only call the function.There

How to make user defined function as library function in c

Step:1

Function in c with no parameter and not returning any value ?

Example:void world1(); //function declarationvoid world2(); //function declarationchar c='*';int i,j;void main(){char *msg="I KNOWN FUNCTION";clrscr();world1(); //function callprintf("%c%22s%7c",c,msg,c);world2(); //function callgetch();}void world1() //function definition{int a=-1;for(i=0;i<15;i++){a++;for(j=0;j<30;j++){if(j>=(15-a) && j<(15+a)){printf(" ");}else{printf("%c",c);}}

Function in c has parameter but not returning any value

void swap(int,int);void main(){int a=10,b=15;clrscr();printf("Befor swap a=%d ,b=%d",a,b);swap(a,b);printf("\nAfter swap a=%d ,b=%d",a,b);getch();}void swap(int a,int b){int c;c=a;a=b;b=c;}Output:Before swap a=10,b=15After swap a=10,b=20Explanation: a and b are auto variable (default storage class is auto) .Here its scope is only within main function.After the main function both a and b will

Function in c with parameter and returning a value.

void main(){int a=1,b=5,c;clrscr();c=operation(a,b);printf("%d",c);getch();}int operation(int a,int b){int c;c=++a * ++a * b++;return c;}Output: 45Note. Any function can return only one value at a time. If return type is int then there is not necessity of function declaration.

What is main function in c?

Every c program starts with a main function and end with null statement.

Properties of main function:

1. Any c program can have only one main function.

2. main function is called by operating system.

3. main is not keyword of c. So any variable name can be main.

4. Programmer can also call the main function.

5. Default return type of main function is int and

To be a good programmer is very necessary to understand the memory structure.

Memory related question of c programming

(1) What will output:
void main()
{
int a=5,b=6,c=7;
printf(“%d,%d,%d”);
}
Ans:
Output: 7 6 5
Explanation:
Default sotrage class int a=5 is auto.Since it automatic variable it will create in the stack area.
It will store in the stack as

Stack always follows LIFO datastructure.
In the printf statement name of variable is not written explicitly.So default output will content of

Definition
of HCF (Highest
common factor):



HFC is also called greatest
common divisor (gcd).
HCF of two numbers is a largest positive numbers which can divide both numbers
without any remainder.  For example HCF
of two numbers 4 and 8 is 2 since 2 is the largest positive number which can
dived 4 as well as 8 without a remainder. 



Logic
of HCF or GCD of any two numbers:



In HCF we try
