Computer General

Switch statement Switch : it's like if and else if statement, but it is a lot more organized to work with and read int main() { using namespace std; int x; cout
Logical OR operator OR : one of those options is true, then the whole statement is true. (||) #include #include int main() { using namespace std; cout
The if Statement If : give the program an option#include int main(){using namespace std;int var = 16;if (var < 30) //if it's false not gonna run the statement{cout
Address Operator & Pointer Address Operator : it shows where in the memory the variable is stored #include int main(){using namespace std;int f = 10; //make variablesint e = 2;//output on the screen?cout
Beginning Loop repetitive task ----> use loop!#include int main(){using namespace std;int x;for(x=0;x
Beginning Arrays Array is a variable that holds a bunch of values in it.(multiple values saved in a single variable)Simple! and Useful! #include #include int main(){using namespace std;/*1. type what kind of the value of the array2. name3. square brackets--> how many values it can store*/int ages[3]; //3 onlyages[0] = 21;ages[1] = 19;ages[2] = 9;/*same as====> int ages[3] = {21,19,9};: faster, easier, and quicke..
User Defined Functions What if we make our own functions..1. First we need function prototype. It tells C++, "Hey, I will make my own function!"2. name of the function--> myfunc3. (declare the type of arguments): void myfunc(int);===> This should be above the main function4. Find the function and pretty much make the functionvoid myfunc(int x){using namespace std;cout
Beginning Math Functions We are going to use another library Then we can use all math related library provided by C++#include #include int main(){using namespace std;double num1; //real number in c++cout
How to start C++ for beginners As you might know, we should have a developing tool and a debugger in order to start to program C++.Go to google -> Find CodeBlock -> Click download -> Click Download Binary -> Download IDE binary file by different OS environment. #include // preprocessor directive ==> File!using namespace std; //standard library : another thing that is built in C++ ==> Library!int main(){ //What type of data yo..
