Explanation / Answer

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main(void)
{
FILE *filePointer;
double arrayData[4];
double maxAcc = 0;
   double positiveAcc = 0;
char buffer[256];
   // opening file
filePointer = fopen("rocket.txt", "r");

if(filePointer == NULL)
{
fprintf(stderr,"Unable to open file");
exit(EXIT_FAILURE);
}

while( fgets(buffer,sizeof(buffer),filePointer) != NULL )
{
       // reading line by line
sscanf(buffer, "%ld %1d %1d %1d", &arrayData[0], &arrayData[1], &arrayData[2], &arrayData[3]);
       // calculating maximum acceleration
       if(arrayData[0] > maxAcc){
           maxAcc = arrayData[0];
       }
       if(arrayData[1] > maxAcc){
           maxAcc = arrayData[1];
       }
       if(arrayData[2] > maxAcc){
           maxAcc = arrayData[2];
       }
       if(arrayData[3] > maxAcc){
           maxAcc = arrayData[3];
       }
       // calculating positive acceleration
       if((arrayData[1] - arrayData[0] ) > positiveAcc){
           positiveAcc = arrayData[1] - arrayData[0];
       }
       if((arrayData[2] - arrayData[1] ) > positiveAcc){
           positiveAcc = arrayData[2] - arrayData[1];
       }
       if((arrayData[3] - arrayData[2] ) > positiveAcc){
           positiveAcc = arrayData[3] - arrayData[2];
       }
      
}

// closing file
   fclose(filePointer);
   // printing results
   printf("Maximum acceleration: %ld ",maxAcc);
   printf("Positive acceleration: %ld ",positiveAcc);
return 0;
}
