BASIC TRICKS

 #include<stdio.h> #include<conio.h> void main() { int age; clrscr(); printf("enter your age to check you are elizable for voting or not="); scanf("%d",&age); if(age>18) { printf("%d you are elizable", age); } else { printf("you are not elizable for vote",age); } getch(); }

#include<stdio.h> #include<conio.h> void main() { int a; printf("Enter a value which you want to check="); scanf("%d",&a); if(a%2==0) { printf("a is even"); } else { printf("a is odd"); } getch(); }

#include<stdio.h> #include<conio.h> void main() { char a; printf("enter a character="); scanf("%c",&a); printf("a=%d",a); getch(); }

#include<stdio.h> #include<conio.h> void main() { int p,t,r,i; clrscr(); printf("enter the value for p="); scanf("%d",&p); printf("enter the value for t="); scanf("%d",&t); printf("enter the value for r="); scanf("%d",&r); i=p*t*r/100; printf("interest is==%f", i); getch(); }

    what is printf() and scanf () roll in C language  ? printf() and scanf() functions are inbuilt library functions in C programming language which are available in C library by default. These functions are declared and related macros are defined in “stdio.h” which is a header file in C language. We have to include “stdio.h” file as shown in below C program to make use of these printf() and scanf() library functions in C language. printf() and scanf() are basic function of C language. 

#include<stdio.h> #include<conio.h> void main() { int a,b,sum=0; clrscr(); printf("enter a value for a="); scanf("%d",&a); printf("enter value for b="); scanf("%d",&b); sum=a+b; printf("%d",sum); getch(); }

#include<stdio.h> #include<conio.h> void main() { printf("Hello....its our first program...!!!"); getch(); }
