How to:
Write a program that computes for the least number of 100,
50, 20, 10, 5, 1, 0.5, 0.25, 0.10, 0.05, & 0.01 bills and coins
equivalent to a given amount (assumed positive, max of 999.99, and assumed
max of 2 digits in the decimal part).

C O D E :
main()
{  float fAmount;
   int nAmt, nAmou;
   int nHun, nFif, nTwe, nTen, nFive, nOne;
   int nCfif, nCtwe, nCten, nCfive, nCone;
   printf("Please enter the amount in pesos: ");
   scanf("%f", &fAmount);
  
   nAmou = fAmount / 1;

   nHun = nAmou / 100;
   nFif = nAmou % 100 / 50;
   nTwe = nAmou % 100 % 50 / 20;
   nTen = nAmou % 100 % 50 % 20 / 10;
   nFive = nAmou % 100 % 50 % 20 % 10 / 5;
   nOne = nAmou % 5;

   nAmt = fAmount*100; 

   nCfif = nAmt % 100 / 50;
   nCtwe = nAmt % 100 % 50 / 25;
   nCten = nAmt % 100 % 50 % 25 / 10;
   nCfive = nAmt % 100 % 50 % 25 % 10 / 5;
   nCone = nAmt % 5;

   printf("no. of 100 peso bills    = %dn", nHun);
   printf("no. of 50 peso bills     = %dn", nFif);
   printf("no. of 20 peso bills     = %dn", nTwe);
   printf("no. of 10 peso coins     = %dn", nTen);
   printf("no. of 5 peso coins      = %dn", nFive);
   printf("no. of 1 peso coins      = %dn", nOne);

   printf("no. of 50 centavo coins  = %dn", nCfif);
   printf("no. of 25 centavo coins  = %dn", nCtwe);
