return 0;
}
output:- Hello, World!
Objective: Write simple input output programs using library functions
printf, scanf, getch
Required apparatus:Computer,turbo C++ software.
programme:
#include <stdio.h>#include <conio.h> void main();{int a;float b;clrscr();printf("Enter any two numbers: ");scanf("%d %f",&a,&b);printf("%d %f",a,b);getch();}Output
Enter any two numbers:103.5EXP-3
Objective: Write simple programme on if statement.
Required apparatus:Computer,turbo C++ software.
programme:
Example
#include<stdio.h>
#include<conio.h>
void main()
{
int a=10;
if(a<=10)
{
printf("a is less than 10");
}
getch();
}
Output
a is less than 10EXP-4
Objective: Write simple programme on if-else statement.
Required apparatus:Computer,turbo C++ software.
programme:
Example
#include<stdio.h>
#include<conio.h>
void main()
{
int time=10;
clrscr();
if(time>12)
{
printf("Good morning");
}
else
{
printf("Good after noon");
}
getch();
}
Output
Good morningEXP-5
Objective: Write simple programme on switch statement.
Required apparatus:Computer,turbo C++ software.
programme:
Example
of switch case
#include<stdio.h>
#include<conio.h>
void
main()
{
int
ch;
clrscr();
printf("Enter
any number (1 to 7)");
scanf("%d",&ch);
switch(ch)
{
case 1:
printf("Today
is Monday");
break;
case 2:
printf("Today
is Tuesday");
break;
case 3:
printf("Today
is Wednesday");
break;
case 4:
printf("Today
is Thursday");
break;
case 5:
printf("Today
is Friday");
break;
case 6:
printf("Today
is Saturday");
break;
case 7:
printf("Today
is Sunday");
break;
default:
printf("Only
enter value 1 to 7");
}
getch();
}
Output
Enter
any number (1 to 7): 5 Today is Friday
EXP-6
Objective: Write simple programme on for loop.
Required apparatus:Computer,turbo C++ software.
programme:
Example of for loop
#include<stdio.h>
#include<conio.h>
void main()
{
int i;
clrscr();
for(i=1;i<5;i++)
{
printf("\n%d",i);
}
getch();
}
Output
1234EXP-7
Objective: Write simple programme on while loop.
Required apparatus:Computer,turbo C++ software.
programme: Example of while loop
#include<stdio.h>
#include<conio.h>
void main()
{
int i;
clrscr();
i=1;
while(i<5)
{
printf("\n%d",i);
i++;
}
getch();
}
Output
1234
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
