Step 1 Define the program headers and the variables
#include
#include
#include
#include
void main()
{
char prompt;
float a,b,c,d,e;
float average,total;
Step 2 Request the numbers from the user by input
printf("Enter in five numbers \n\r");
scanf("%f",&a);
scanf("%f",&b);
scanf("%f",&c);
scanf("%f",&d);
scanf("%f",&e);
Step 3 Calculate the Sum of A,B,C,D,E
total=a+b+c+d+e;
Step 4 Compute the average
average= total/5;
Step 5 Display the results and Stop the program
printf(" The average is %f \n\r",average);
printf("Press any key to exit \n\r");
scanf("\n%c",&prompt);
}
The total program is as follows
#include
#include
#include
#include
void main()
{
char prompt;
float a,b,c,d,e;
float average,total;
printf("Enter in five numbers \n\r");
scanf("%f",&a);
scanf("%f",&b);
scanf("%f",&c);
scanf("%f",&d);
scanf("%f",&e);
total=a+b+c+d+e;
average= total/5.0;
printf(" The average is %f \n\r",average);
printf("Press any key to exit \n\r");
scanf("\n%c",&prompt);
}
We could replace the following two lines
total=a+b+c+d+e;
average= total/5.0;
with
average =(a+b+c+d+e)/5.0;
Hence the program becomes
#include
#include
#include
#include
void main()
{
char prompt;
float a,b,c,d,e;
float average;
printf("Enter in five numbers \n\r");
scanf("%f",&a);
scanf("%f",&b);
scanf("%f",&c);
scanf("%f",&d);
scanf("%f",&e);
average =(a+b+c+d+e)/5.0;
printf(" The average is %f \n\r",average);
printf("Press any key to exit \n\r");
scanf("\n%c",&prompt);
}
