}
1.5)Give the radious of a circle, write a program to compute and display its area. Use a symbolic constraint to define the Π value are assume a suitable value for radius.
#include<stdio.h>
#include<conio.h>
#define pi 3.1416
void main()
{
clrscr();
float area,n;
printf("\nEnter the radius of the circle:");
scanf("%f",&n);
area=pi*pow(n,2);
printf("The area is=%f",area);
getch();
}
1.6)Write a program to output the following multiplication table:.
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
. .
. .
5 × 10 = 50
Solution :#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
for(int j=1;j<=10;j++)
printf("5 x %d=%d\n\n",j,(5*j));
getch();
}
1.7)Give two integers 20 & 100, write a program that uses a function add() to add this two number and sub to fiend the difference of these two numbers and then display the sum and difference in the following form :20+10=30
20-10=10
Solution :
#include<stdio.h>
#include<conio.h>
void add(int a,int b)
{
int c;
c=a+b;
printf("%d+%d=%d\n",a,b,c);
}
void sub(int a,int b)
{
int c;
c=a-b;
printf("%d-%d=%d",a,b,c);
}
void main()
{
clrscr();
int a,b;
printf("\nEnter two number's:");
scanf("%d%d",&a,&b);
add(a,b);
sub(a,b);
getch();
}
1.8)Give the values of three variables a, b, and c, write a program to compute and display the value of x, where x=a/(b-c)
Execute your program for the following values :
a) a=250, b=85, c=25
b) a=300, b=70, c=70
Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
float a,b,c,x;
printf("\nEnter three value's:");
scanf("%f%f%f",&a,&b,&c);
if(!(b-c))
printf("X=ì");
else
{
x=a/(b-c);
printf("X=%f",x);
}
getch();
}

2.1)Write a program to determine and print the some of the following harmonic series for a given value of n:
1+1/2+1/3+..................1/nThe value of n should be given interactively through the terminal.
Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
float i,sum=0,n;
printf("Enter your range:\n");
scanf("%f",&n);
for(i=1;i<=n;i++)
sum=sum+1/i;
printf("sum=%f",sum);
getch();
}
2.2)Write a program to read the price of an item in the decimal from (like 15.95) and print the output in price (like 1595 paise).Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
float a,b,n;
printf("Enter the price of your item:");
scanf("%f",&a);
n=a*100;
printf("your price is %.3f paisa",n);
getch();
}
2.3) Write a program that prints the even numbers from 1 to 100.Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
for(int i=2;i<=100;i++)
if(!(i%2))
printf("%d ",i);
getch();
}
2.4) Write a program that requests two float type numbers from the user and then divides the first number by the second and display the result along with the numbers.Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
float a,b,c;
printf("\nEnter two float type number:");
scanf("%f%f",&a,&b);
c=a/b;
printf("%.3fö%.3f=%.3f",a,b,c);
getch();
}
2.5) The price of one kg rice is Rs. 16.75 and one kg of sugar is Rs. 15. Write a program to get these values from the user and display the prices as follows:***LIST OF ITEMS*** Item Price Rice Rs 16.75 Sugar Rs 15.00Solution :
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
float a,b;
printf("\nEnter the price of rice and sugar in Kg:");
scanf("%f%f",&a,&b);
printf("\n***LIST OF ITEMS***\n");
printf("Item Prize\n");
