Question

C Programming:

Problem 1:

Write a function that returns the index of the largest value stored in an array-of- double. Test the function in a simple program

Problem 2:
Write a function that returns the difference between the largest and smallest elements of an array-of-double. Test the function in a simple program

Answer 1

1.

Program:

#include <stdio.h>

int max_index(double arr[], int n);

int main(void) {

int n,index; // variable Declaration

double x[50];

printf("Enter number of elements in the array: ");

scanf("%d",&n); // Accept the number

printf("Enter array elements: \n");

for(int i=0; i<n; i++) // loop to accept array elements

scanf("%lf",&x[i]); // accept array elements

index = max_index(x, n); // calling function

printf("Max element index is : %d\n",index); // print max index

return 0;

}

int max_index(double arr[], int n){

int index; // variable Declaration

double max = arr[0]; // variable Declaration

for(int i=0; i<n; i++) { // loop to find max element index

if(max<arr[i]) {

max=arr[i];

index = i; // index contain max element index

}

}

return index; // return max index

}

Output:

2.

Program:

#include <stdio.h>

double diffLargeSmall(double arr[], int n);

int main(void) {

int n; // variable Declaration

double x[50];

printf("Enter number of elements in the array: ");

scanf("%d",&n); // Accept the number

printf("Enter array elements: \n");

for(int i=0; i<n; i++) // loop to accept array elements

scanf("%lf",&x[i]); // accept array elements

double difference = diffLargeSmall(x, n); // calling function

printf("Max element index is : %.2lf\n",difference); // print max index

return 0;

}

double diffLargeSmall(double arr[], int n){

double large = arr[0]; // variable Declaration

double small = arr[0]; // variable Declaration

for(int i=1; i<n; i++) { // loop to find largest and smallest

if(large<arr[i]) {

large=arr[i]; // calculate large

}

if(small>arr[i]) {

small=arr[i]; // calculate small

}

}

return large-small; // return difference of large and small

}

Output:
