Q-1:- Write a program to print your details.
#include<stdio.h>
#include<conio.h>
void main( )
{
clrscr( );
printf( "SIMS");
printf("\nBCA 1st semester");
printf("\nAnubhav");
getch( );
}
Output:-
SIMS
BCA 1 st semester
Anubhav
Q-2:- Write a program to sum of two number.
#include<stdio.h>
#include<conio.h>
void main( )
{
int a,b,sum;
clrscr( );
printf("Enter any two number a and b :");
scanf("a=%d,b=%d",&a,&b);
sum=a+b;
printf("\nsum=%d",sum);
getch( );
}
Output:-
Enter any two number a and b:
a=5,b=3
sum=8
Q-3:- Write a program to subtract of two number.
#include<stdio.h>
#include<conio.h>
void main( )
{
int a,b,sub;
clrscr( );
printf("Enter any two number a and b :");
scanf("a=%d,b=%d",&a,&b);
subtract=a-b;
printf("\nsubtract=%d",sub);
getch( );
}
Output:-
Enter any two number a and b:
a=5,b=3
subtract=2
Q-4:- Write a program to multiple two number.
#include<stdio.h>
#include<conio.h>
void main( )
{
int a,b,m;
clrscr( );
printf("Enter any two number a and b :");
scanf("a=%d,b=%d",&a,&b);
m=a*b;
printf("\nm=%d",m);
getch( );
}
Output:-
Enter any two number a and b:
a=5,b=3
m=15
Q-5:- Write a program to swap the value of two variable by using third variable.
#include<stdio.h>
#include<conio.h>
void main( )
{
int a,b,c
clrscr( );
printf("Enter any two number a and b :");
scanf("a=%d,b=%d",&a,&b);
c=a;
a=b;
b=c;
printf("after swaping the value of a and b:");
printf("\na=%d,b=%d",a,b);
getch( );
}
Output:-
Enter any value of a and b:
a=5,b=6
after swaping the value of a and b:
a=6,b=5
Q-6:-WAP to find the data(ROLL NUMBER, NAME, DEPARTMENT,COURSE, YEAR OF JOINING) of student according to roll number using structure.
#include<stdio.h>
#include<conio.h>
struct class
{
int rollno;
char name[10];
char department[10];
char course[10];
int yearofjoining;
};
void main( )
{ int i , r;
struct class b[5];
clrscr( );
for(i=0;i<5;i++)
{
scanf("%d%s%s%s%d",&b[i].rollno,&b[i].name,
&b[i].department,&b[i].course,
&b[i].yearofjoining);
}
printf("Enter the roll number:");
scanf("%d",&r);
for(i=0;i<5;i++)
{ if(r==b[i].rollno)
{
printf("%d\n%s\n%s\n%s\n%d",b[i].rollno,
b[i].name,b[i].department,b[i].course,
b[i].yearofjoining);
break;
}
else
{
printf("roll number is not found !");
}
}
getch( );
}
Output:-
1 abhi computer bca 2021
2 abhijeet computer bca 2021
3 Atul computer bca 2021
4 Anubhav computer bca 2021
5 adesh computer bca 2021
Enter the roll number: 4
4
Anubhav
computer
bca
2021
Q-7-Write a program to find prime number.
#include <stdio.h>
int main()
{
int n, i, flag = 0;
printf("Enter a positive integer: ");
", &n);
// 0 and 1 are not prime numbers
// change flag to 1 for non-prime number
if (n == 0 || n == 1)
flag = 1;
for (i = 2; i <= n / 2; ++i) {
// if n is divisible by i, then n is not prime
// change flag to 1 for non-prime number
if (n % i == 0) {
flag = 1;
break;
}
}
// flag is 0 for prime numbers
if (flag == 0)
printf("%d is a prime number.", n);
else
printf("%d is not a prime number.", n);
return 0;
}
