Unit-III:Using control statements
1.Write a program to print 1 to 10 numbers using a while loop.
#include <stdio.h>
#include <conio.h>
void main(){
int i=1;
while(i<=10){
printf("%d\n",i);
i++;
}
getch();
}

2.Write a program to read any 7 numbers and print the average value using a for loop.
#include <stdio.h>
#include <conio.h>
void main(){
int i,a;
float sum=0,avg;
for(i=0;i<8;i++){
printf("Enter number:");
scanf("%d",&a);
sum+=a;
}
avg=sum/7;
printf("Average:%f",avg);
getch();
}
Enter number:23
Enter number:65
Enter number:23
Enter number:63
Enter number:98
Enter number:23
Enter number:54
Average:57.571430
3.Write a program to reverse a given integer number.
#include <stdio.h>
#include <conio.h>
void main(){
int num,rem;
printf("enter an integer:");
scanf("%d",&num);
while (num!=0){
rem = num%10;
num=num/10;
printf("%d",rem);
}
getch();
}
enter an integer:440
044
4.Write a program to print Fibonacci series of given number.
#include <stdio.h>
#include <conio.h>
void main(){
int a=0,b=1,i,sum;
for(i=0;i<9;i++){
printf("%d\t",a);
sum=a+b;
a=b;
b=sum;
}
getch();
}

5.Write a program to find factorial of a number.
#include <stdio.h>
#include <conio.h>
void main(){
int i,f=1,n;
printf("enter num=");
scanf("%d",&n);
for(i=n;i>=1;i--){
f=f*i;
}
printf("factorial=%d",f);
getch();
}
enter num=5
factorial=120
6.Write a program to check whether a number is a Krishnamurthy number or not. Krishnamurthy number is one whose sum of factorial of digits equals the number. Example:145 1! + 4! + 5! = 1 + 24 + 120 = 145
#include <stdio.h>
#include <conio.h>
void main(){
int num,i,j,count=0,f=1,x,sum=0,mult,y,p;
printf("enter number:");
scanf("%d",&num);
x=num;
y=num;
while(x!=0){
x=x/10;
count++;
}
for(i=1;i<=count; i++){
p=num%10;
num=num/10;
for(j=p;j>=1;j--){
f=f*j;
}
printf("factorial of %d is %d\n",p,f);
sum=sum+f;
f=1;
}
printf("sum=%d\n",sum);
if(sum == y){
printf("%d is Krishnamurthy number.",y);
}
else{
printf("%d is not Krishnamurthy number.",y);
}
getch();
}
factorial of 5 is 120
factorial of 4 is 24
factorial of 1 is 1
sum=145
145 is Krishnamurthy number.
7.Write a program to check whether the number is Armstrong or not. Example:153---- 13+ 53+33= 1 + 125 + 27 153
#include <stdio.h>
#include <conio.h>
void main(){
int num,i,count=0,x,sum=0,mult,y,p;
printf("enter number:");
scanf("%d",&num);
x=num;
y=num;
while(x!=0){
x=x/10;
count++;
}
for(i=1;i<=count; i++){
p=num%10;
num=num/10;
mult=p*p*p;
printf("cube of %d is %d\n",p,mult);
sum=sum+mult;
}
printf("sum=%d\n",sum);
if(sum == y){
printf("%d is Armstrong number.",y);
}
else{
printf("%d is not Armstrong number.",y);
}
getch();
}
enter number:153
cube of 3 is 27
cube of 5 is 125
cube of 1 is 1
sum=153
153 is Armstrong number.
8.Write a program to list all prime numbers within given range.
#include <stdio.h>
#include <conio.h>
void main() {
int start, end;
printf("Enter the starting point of the range: ");
scanf("%d", &start);
printf("Enter the ending point of the range: ");
scanf("%d", &end);
printf("Prime numbers between %d and %d are:\n", start, end);
for (int i = start; i <= end; ++i) {
int isPrime = 1;
for (int j = 2; j < i; ++j) {
if (i % j == 0) {
isPrime = 0;
break;
}
}
if (isPrime) {
printf("%d\n", i);
}
}
getch();
}
Enter the starting point of the range: 23
Enter the ending point of the range: 60
Prime numbers between 23 and 60 are:
23
29
31
37
41
43
47
53
59
9.Write a program to draw following patterns:(!!!:don't copy paste whole code.It will gives error.Copy code according to pattern)
