bookArithmetic Operators Practice

These five mathematical operators (+, -, *, /, and %) serve to carry out various mathematical operations. They work as you expect it to work and they also account for the order of the operation and paranthes. So the multiplication goes first and so on.

cpp

main

copy

              
1234567

            
#include<iostream>

int main()
{
    // Write any math expression you want
	std::cout <<  ___ << std::endl;
}

The division operator (/) returns only the integer part of the result, discarding any remainder. For instance, when dividing 10 by 3, the result is 3, not 3.333... To obtain the desired division result with decimals (e.g., 10 / 3 = 3.333), it is necessary for at least one of the operands to be of a double or float data type.

cpp

#include <iostream>

int main()
{
	std::cout << 5 / 2 << std::endl;
	std::cout << 5. / 2 << std::endl;
}

The modulo operator (%) calculates and returns the remainder resulting from a standard division operation.

	std::cout << 15 % 8 << std::endl;
}
