Question

In the C language

Double any element's value that is less than controlVal. Ex: If controlVal = 10, then dataPoints = {2, 12, 9, 20} becomes {4, 12, 18, 20}.

#include <stdio.h>

int main(void) {
const int NUM_POINTS = 4;
int dataPoints[NUM_POINTS];
int controlVal;
int i;

scanf("%d", &controlVal);

for (i = 0; i < NUM_POINTS; ++i) {
scanf("%d ", &(dataPoints[i]));
}

/* Your solution goes here */

for (i = 0; i < NUM_POINTS; ++i) {
printf("%d ", dataPoints[i]);
}
printf("\n");

return 0;
}

#include <stdio.h>

int main(void)
{
const int NUM_POINTS = 4;
int dataPoints[NUM_POINTS];
int controlVal;
int i;
  
scanf("%d", &controlVal);
  
for (i = 0; i < NUM_POINTS; ++i)
{
scanf("%d ", &(dataPoints[i]));
}
  
//if the dataPoint value is less than controlVal then double it
for (i = 0; i < NUM_POINTS; ++i)
{
if(dataPoints[i]<controlVal)
{
dataPoints[i] = 2 * dataPoints[i];
}
}
  
for (i = 0; i < NUM_POINTS; ++i)
{
printf("%d ", dataPoints[i]);
}
printf("\n");
  
return 0;
}
