Exercise 1: Print Numbers from 1 to N
Description: Write a program that takes a positive integer N as input and prints all the numbers from 1 to N.
Input Example:
Enter a positive integer N: 5
Output Example:
Numbers from 1 to 5:
1
2
3
4
5
Exercise 2: Calculate Factorial
Description: Write a program that takes a positive integer N as input and calculates the factorial of N.
Input Example:
Enter a positive integer N: 4
Output Example:
Factorial of 4 is 24
Exercise 3: Print Multiplication Table
Description: Write a program that takes a positive integer N as input and prints the multiplication table for N.
Input Example:
Enter a positive integer N: 7
Output Example:
Multiplication table for 7:
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
...
7 x 10 = 70
Exercise 1 Complete Code:
#include <stdio.h>
int main() {
int N;
printf("Enter a positive integer N: ");
scanf("%d", &N);
printf("Numbers from 1 to %d:\n", N);
for (int i = 1; i <= N; ++i) {
printf("%d\n", i);
}
return 0;
}
Exercise 2 Complete Code:
#include <stdio.h>
int main() {
int N;
unsigned long long factorial = 1;
printf("Enter a positive integer N: ");
scanf("%d", &N);
for (int i = 1; i <= N; ++i) {
factorial *= i;
}
printf("Factorial of %d is %llu\n", N, factorial);
return 0;
}
Exercise 3 Complete Code:
#include <stdio.h>
int main() {
int N;
printf("Enter a positive integer N: ");
scanf("%d", &N);
printf("Multiplication table for %d:\n", N);
for (int i = 1; i <= 10; ++i) {
printf("%d x %d = %d\n", N, i, N * i);
}
return 0;
}
