}
4. Write a program using C language to display reverse
order from the entered number.
[ex: Enter 5 and display the result: 5 4 3 2 1)
Solution:
#include <stdio.h>
int main() {
int n, i;
printf("Enter the value of n: ");
scanf("%d", &n);

for (i = 5;
i <= 15; i++)
printf("%d ", i);
printf("\n");
return 0;
}
6. Write C programming to calculate the sum of first
10 natural numbers.
Solution:
#include <stdio.h>
int main()
{
int i, sum =
0;
for (i = 1;
i <= 10; i++)
sum +=
i;
printf("The sum of the first 10 natural numbers is: %d\n",
sum);
return 0;
}
7. Write C program to display only multiples of 5 from
1 to 50.
Solution:
#include <stdio.h>
int main()
{
int i;
printf("Multiples of 5 from 1 to 50:\n");
for (i = 1;
i <= 50; i++)
if (i %
5 == 0)
printf("%d ", i);
return 0;
}
8. Write C programming to display odd numbers from 1
to 19.
Solution:
#include <stdio.h>
int main()
{
int i;
printf("1 to 19 odd numbers:\n");
for (i = 1;
i <= 19; i += 2)
printf("%d ", i);
printf("\n");
return 0;
}
9. Write C programming to display first 15 odd
numbers.
Solution:
#include <stdio.h>
int main()
{
int i;
printf("First 15 even numbers:\n");
for (i = 2;
i <= 30; i += 2)
printf("%d ", i);
printf("\n");
return 0;
}
10. Write a C program to count and print all odd
numbers between 1 and 50.
Solution:
#include <stdio.h>
int main()
{
int i, sum =
0;
printf("Odd numbers between 1 and 50 are:\n");
for (i = 1;
i <= 50; i += 2)
{
printf("%d ", i);
sum
+= i;
}
printf("\nSum of odd numbers between 1 and 50: %d\n", sum);
return 0;
}
11. To display the reverse order of odd numbers from
19 to 1 write a programming using C language.
Solution:
#include <stdio.h>
int main()
{
int i;
printf("Odd numbers from 19 to 1:\n");
for (i = 19;
i >= 1; i -= 2)
printf("%d\n", i);
return 0;
}
12. Extend the program to calculate the sum of the
first 15 odd numbers.
Solution:
#include <stdio.h>
int main()
{
int i, sum =
0;
printf("Odd numbers between 1 and 15 are:\n");
for (i = 1;
i <= 15; i += 2)
{
printf("%d\n", i);
sum
+= i;
}
printf("\nSum of odd numbers between 1 and 15: %d\n", sum);
return 0;
}
13. Write C programming to print the first 15 odd
numbers with their squares.
Solution:
#include <stdio.h>
int main()
{

if (num % 2
== 0)
printf("%d is an even number.\n");
else
printf("%d is an odd number.\n");
return 0;
}
