Exercise 1:

Write a program (WAP) that will print following series upto N^th terms.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, ……,N.

Sample Input	Sample Output
2	1, 2
3	1, 2, 3
5	1, 2, 3, 4, 5

    int main() {

 

       int n, i;

       printf(" Inter The Nth term N = ");

       scanf_s("%d", &n);

       for (i = 1; i <= n; i++ )

       {

             printf("%d", i);

Exercise 4:

Write a program (WAP) that will take N numbers as inputs and compute their average.
[N:B: Restriction: Without using any array ]

Sample Input	Sample Output
3 10   20   30.5	AVG of 3 inputs: 20.166667
2 11.1   22.4	AVG of 2 inputs: 16.750000

#include<stdio.h>

int main() {

 

       int i, n;

       float num, sum =0, avrg;

 

       printf(" How many numbers you wwant to avrage = ");

       scanf_s("%d", &n);

 

       for (i = 1; i <= n; i++)

       {

             printf(" Enter a number = ");

             scanf_s("%f", &num);

 

             sum = sum + num;

 

 

       }

       avrg = sum / n;

       printf("The average of numbers is = %.3f\n", avrg);

 

       return 0;

}

 

 

Exercise 5:

Write a program (WAP) that will take two numbers X and Y as inputs. Then it will print the square of X and increment (if XY) X by 1, until X reaches Y. If and when X is equal to Y, the program prints “Reached!”

Sample Input	Sample Output
10   5	100, 81, 64, 49, 36, Reached!
5   10	25, 36, 49, 64, 81, Reached!
10   10	Reached!

	#include <stdio.h> int main() {          int x, y, i ;               printf(" Enter Number X = ");        scanf_s("%d", &x);        printf(" Enter Number y = ");        scanf_s("%d", &y);          while (x!=y)        {              if (x < y)              {                     printf("%d",x*x );                     printf(",");                     x++;                 }                if (x > y)              {                     printf("%d",x*x );                     printf(",");                     x--;              }                       }          if (x = y)        {              printf("Reached!");        }            return 0; }
