1. This is a programe for c++.You can find out someone's sallery detail with this programme:

#include<stdio.h>
#include<conio.h>
main()
{
float basic,medical,others,fund,total,year;
clrscr();
printf("Please Enter The Basicn");
scanf("%f",&basic);
basic=basic;
medical=basic*.1;
fund=basic*.15;
others=basic*.2;
total=basic+medical-fund+others;
year=total*12;
printf("Basic=%fn",basic);
printf("Medical=%fn",medical);
printf("Others=%fn",others);
printf("Monthly Total Sallery=%fn",total);
printf("Yearly Total Sallery=%fn",year);
printf("Profident Fund Per Month=%fn",fund);
getch();
}

2. This Programme is to display some text only.
#include<stdio.h>
#include<conio.h>
main()
    {
clrscr();
printf(" AAAAAAAAAAAAn");
printf(" AAAAAAAAAAn");
printf("   AAAAAAAAn");
printf("    AAAAAn");
printf("     AAAn");
printf("      An");
getch();
    }

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
printf("AAAAAAAAAAAAn AAAAAAAAAAn AAAAAAAAn   AAAAAn    AAAn     A");
getch();
}

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a,b,c;
a=5;
b=8;
c=a+b;
printf("the result is=%d",c);
getch();
}

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a,b,c;
printf("input the value of a=");
scanf("%d",&a);
printf("input the valu of b=");
scanf("%d",&b);
c=a+b;
printf("input the sumation is=%d",c);
getch();
}

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int i,sum;
sum=0;
for(i=1;i<100;i++)
sum=sum+i;
printf("the sum is=%d",sum);
getch();
}

#include<stdio.h>
#include<conio.h>
void main()
{
int sum,i,n;
clrscr();
sum=0;
printf("Enter The Value Of n=");
scanf("%d",&n);
for(i=1;i<=n;i++)
sum=sum+i;
printf("The sumation is=%d",sum);
getch();
}

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int bangla,english,math,social,science,total;
printf("Give The Mark of bangla=");
scanf("%d",&bangla);
printf("Give The Marke of english=");
scanf("%d",&english);
printf("give the mark of math=");
scanf("%d",&math);
printf("give the mark of social=");
scanf("%d",&social);
printf("give the mark of science=");
scanf("%d",&science);
total=bangla+english+math+social+science/;
printf("bangla+english+math+social+science=%d",total);
getch();
}

#include<stdio.h>
#include<conio.h>
#define PI 3.14
void main()
{
clrscr();
float area,r;
printf("input the value of r=");
scanf("%f",&r);
area=PI*r*r;
printf("the area of the circle=%f",area);
getch();
}
