Intro To C++/Playing with operator

Variables Making statement Basic Math C++ can be used to do basic math. The operators used in the basic math are listed in the table below. Operator Operation Arithmetic Operator addition Subtraction Multiplication Division Modulus Increment DecrementAssignment Operator "" is equivalent to "" "" is equivalent to """" is equivalent to "" "" is equivalent to """" is equivalent to """" is equivalent to ""Comparison Operator Equality Inequality Greater thanLess than Greater than or equal to Less than or equal to Logical Operator Logical AND Logical OR Logical NOT Basic math operators in C++ have some distinguishing features: Bulleted list item Bulleted list item Bulleted list item Part of Basic math operation is demonstrated in the C++ program below: #include <iostream>; using namespace std; int main{ int a=4, b=9, c=0; cout << "Addition result(a+b):"<<(a+b)<< endl; cout << "Multiplication result(a*b):"<<(a*b)<< endl; cout << "Multiplication & assign: a *=b(4*9) a="<< a*=b << endl; cout << "lesser comparision: a < b "<< (a<b) << "true"<< endl; cout << "And logic: (a && a)" << (a && a) << "(true)" << endl; } Checking Size The memory size of any variable can be discovered using the C++ sizeof operation.The sizeof operator syntax is look like this: sizeof(var) The sizeof operator is demonstrated in the program as follows: #include <iostream> using namespace std; int main(){ } Casting Data Types Any data-types except "string" could be converted to another data type through "casting". Casting syntax in C++ looks like this: variable-name=static-cast <data-type> variable-name Casting with C++ form is demonstrated in the program as follows: #include <iostream> using namespace std; int main(){ } Further reading 75%
