bookSimple Math

To perform arithmetic operations on variables and values C++ supports the following arithmetic operators:

Let’s try:

12345
int sum = 10 + 3; // 13 int dif = 10 - 3; // 7 int mul = 10 * 3; // 30 int div = 10 / 3; // 3 int mod = 10 % 3; // 1
copy

By division, any remainder was dropped since we assign the result to the int variable which doesn’t contain any decimals.

You can use all operations above to perform calculations on values, variables, or between variable and value:

123
double a = 32 + 13; // 45 double b = a + 25; // 45 + 25 = 70 double c = a + b; // 70 + 45 = 115
copy
Tarefa

Robin has 18$ and Ted has 12$. How much money has each of them in average?

  1. Calculate the sum of their money and assign it to the variable sum.
  2. Divide the sum by 2 (number of people) to find the average and assign the result to the variable avr.
  3. Print the variable avr.

Please, don’t forget about semicolon ; at the end of lines.
