Question

Write a C program that calculates the percent saves for a soccer goalie for 4 games and the overall percentage of saves which is saves divided by the sum of goals plus saves

* In this program I used 4 variables of type int, and 1 of type float, and 1 of type char (for the buffer clearing statement required).

* This program requires an introductory statement to the user.

* This program requires a loop structure (a for loop is best).

* The loop requires 3 printf statements: 1 to prompt the user for the "number of goals"; 1 to prompt for "number of saves"; and a third to display the calculated "percent saves".

* The loop also requires 2 scanf statements, and two buffer clearing statements.

* This program requires 3 calculations within the loop - one for the game percent saves, and two accumulators to add up the total saves and total goals for the final calculation.

* This program requires another printf statement (outside the for loop) to display the percent saves for all games.

* The loop index should be used to display the current game calculation.

Answer 1

Solution:

#include<stdio.h>
void main()
{
   int goals[4],saves[4],totalsaves=0,totalgoals=0,i;
   float savespercent,totalsavespercent;

   printf("This program calculates overall percentage of saves by a soccer goalie\n");
   for(i=0;i<4;i++)
   {
       printf("\nEnter number of goals in match %d:",i+1);
       scanf("%d",&goals[i]);
       printf("Enter number of saves in match %d:",i+1);
       scanf("%d",&saves[i]);
       savespercent=(float)saves[i]/(float)goals[i];
       savespercent=savespercent*100.00;
       printf("\nPercentage of saves in match %d is %.2f",i+1,savespercent);
       totalsaves=totalsaves+saves[i];
       totalgoals=totalgoals+goals[i];
   }
   totalsavespercent=(float)totalsaves/(float)totalgoals;
   totalsavespercent=totalsavespercent*100.00;
   printf("\nTotal Percentage of saves in all matches is %.2f\n",totalsavespercent);
}

Output:
