Can you explain a, I don't understand.-CodePudding

#include
Int main ()
{
Float r, x, p, y;
int i;
The scanf (" % f % f % f ", & amp; R, & amp; X, & amp; P);
Y=x;
for(i=1; iY *=(100 + r)/100;
Printf (" % 2 f \ n ", y);
return 0;
}
Especially put x to y here, as well as for statement to understand

According to the annual interest rate r x % deposit, deposit of principal and interest of y=x * p years later (100) (100 + r)/^ p, o y values

Why to define your p into float type?

This is the correct answer to online, I just don't understand

CodePudding user response:

Save the principal and interest of total=p years later the principal * (1 + apr) ^ p, if the annual interest rate is not the absolute Numbers but percentage will be divided by 100, his code is the cycle for power

CodePudding user response:

X on behalf of the principal, r is for interest rates, p represents the number of years, on behalf of p y years later, the total amount of is this meaning?
Y=x, said the total amount of the first and principal
For loop said cycle in p, each cycle a calculated total amount
Y *=(100 + r)/100 is equivalent to y=y * (100 + r)/100, said in a loop, recalculate y,
The calculating formula of y=total amount is RMB yuan gold + gold * interest rates, namely, y=y + y * (r/100)=y * (100 + r)/100
The last print y, retain two decimal

CodePudding user response:

Deposit capital x, just no interest, so p is the total value is the middle of the x y cycle, cycle represents one year at a time, because I was int type, compared to replace p with the same type, float, is your p (int) p is to put the p forced conversion to type int
