Q1. Write a C program to calculate sum of all even elements of a matrix. [15 Marks]

#include<stdio.h>

int main(){

   /* 2D array declaration*/

   int disp[2][3],sum=0;

   /*Counter variables for the loop*/

   int i, j;

   for(i=0; i<2; i++) {

      for(j=0;j<3;j++) {

         printf("Enter value for disp[%d][%d]:", i, j);

         scanf("%d", &disp[i][j]);

      }

   }

   //Displaying sum of all even array elements

   printf("Two Dimensional array elements:\n");

   for(i=0; i<2; i++) {

      for(j=0;j<3;j++) {

             sum=sum+disp[i][j];

         }

      }

   }

printf("sum=%d=", sum);

   return 0;

}

Q2. Write a menu driven program for the following option [25 Marks]

1. Check input number is Armstrong or not

2. Check input number is Perfect or not

#include <stdio.h>

void main()

{

    int fig_code;

    int number, originalNumber, remainder, result = 0;

    int n,i=1,sum=0; 

while(1)

     {

    printf("-------------------------\n");

    printf(" 1 --> Armstrong or not\n");

    printf(" 2 --> Perfect or not \n");

    printf("-------------------------\n");

    printf("Enter the Figure code\n");

    scanf("%d", &fig_code);

    switch(fig_code)

    {

    

    case 1:

        printf("Enter a three digit integer: ");

       scanf("%d", &number);

       originalNumber = number;

    while (originalNumber != 0)

    {

        remainder = originalNumber%10;

        result += remainder*remainder*remainder;

        originalNumber /= 10;

    }

    if(result == number)

        printf("%d is an Armstrong number.",number);

    else

        printf("%d is not an Armstrong number.",number);

        break;

    case 2:

    printf("Enter a number: ");

    scanf("%d",&n);

    while(i<n){

      if(n%i==0)

           sum=sum+i;

         i++;

    }

    if(sum==n)

      printf("%d is a perfect number",i);

    else

      printf("%d is not a perfect number",i);

        

                break;

Q1. Write a C program to find maximum elements of 1D array [15 Marks]

#include <stdio.h>

int main()

{

    int i, n;

    float arr[100];

    printf("Enter total number of elements(1 to 100): ");

    scanf("%d", &n);

    printf("\n");

    // Stores number entered by the user

    for(i = 0; i < n; ++i)

    {

       printf("Enter Number %d: ", i+1);

       scanf("%f", &arr[i]);

    }

    // Loop to store largest number to arr[0]

    for(i = 1; i < n; ++i)

    {

       // Change < to > if you want to find the smallest element

       if(arr[0] < arr[i])
