Double any element's value that is less than minval. ex: if minval = 10, then datapoints = {2, 12,9, 20) becomes {4, 12, 18, 20).

#include

int main(void) {
const int num_points = 4;
int datapoints[num_points];
int minval;
int i;
scanf("%d", & minval);
for (i = 0; i < num_points; ++i)
{ scanf("%d ", & (datapoints[i])); }
for (i = 0; i < num_points; ++i)
{ printf("%d ", datapoints[i]); }
printf("\n");
return 0; }

The correct program to this question can be given as:

Program:

#include <stdio.h>

int main(void) //define main method.

{

  const int NUM_POINTS = 4;  //define constant variable and assign value.

  int dataPoints[NUM_POINTS]; //define array.

  int minVal = 0; //define variable

  int i = 0;  //define variable

  printf("Enter minimum value :"); //message

  scanf("%d",&minVal); //input value from user.

  printf("Enter array elements :");  //message

  for(i = 0;i<NUM_POINTS;++i)  //loop.

  {

     scanf("%d",&(dataPoints[i])); //assign elements in array

  }

  for (i = 0; i < NUM_POINTS; ++i) //loop

  {//conditional statement.

   if(dataPoints[i]<minVal) //check condition.  

   {

   dataPoints[i] = 2*dataPoints[i]; //multiply by 2.

   }

  }

   printf("array elements :"); //message

  for (i = 0; i < NUM_POINTS; ++i) //loop.

  {

     printf("%d ", dataPoints[i]); //print array value.

  }

  return 0;

}

Output:

Enter minimum value :10

Enter array elements :2 12 9 20

array elements :4 12 18 20  

Explanation:

The explanation of the above C language program as follows:

In the program first, we include the header file. Then we define the main method in method we define a variable that is "NUM_POINTS, minVal, dataPoints[] and i". The NUM_POINTS variable uses a const key that is used to make variable constant and we assign a value in this variable. Then we define dataPoints[] variable. It is an array type variable that is used to store user inputs and the minVal is an integer variable that is used for user input and checks the value of the array. Then we define a three for loops in the first loop we insert array elements from the user. In the second loop, we use the condition statement in the if block we compare the value of dataPoints is less than to minVal. If this value is true so, we multiply by 2 in array elements. In the third loop, we print all array elements.

The answer is 1000. because i said so

Answerpage pane; i believe this is a correct answer/ plz check first/// good luck;
