PUSH UPS WITH BLAZE

Description:

At UAB football games, Blaze does push ups after each Blazer score. After the first Blazer touchdown (and point after), Blaze does 7 push ups. After the second touchdown and point after, the score is now 14 and Blaze does 14 push ups. Write a program that calculates how many total push ups Blaze does during the whole game. Assume that only 7 point touchdowns (including the point after) occur. Prompt for the final score and print out how many push ups Blaze has done. Test Case 1 Input (stdin) 21 Expected Output 42 Test Case 2 Input (stdin) 28 Expected Output 70

Program :

#include <stdio.h>

int main()

{

  int a,b,i;

  scanf("%d",&a);

  for(i=7;i<=a;i=i+7)

    b=b+i;

  printf("%d",b);

   

 

return 0;
