Compiler in C Programming
A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer’s processor uses.
Function and Variable Naming in C
Explanation: A C program can have same function name and same variable name. A variable name cannot start with an integer. The C compiler interprets the ‘-‘ and ‘?’ as a minus operator and a question mark operator respectively.
What is Float in C Program?
Float is a shortened term for "floating point." It’s a fundamental data type built into the compiler used to define numeric values with floating decimal points in C, C++, C#, and many other programming languages. Other common data types include int and double.
Reading Formatted Data with Sscanf
How do you Sscanf? In C, sscanf() is used to read formatted data. It works much like scanf() but the data will be read from a string instead of the console.
Format Specifiers:
- %c: single character
- %d: decimal integer
- %e, %E, %f, %g, %G: floating points
- %u: unsigned integer
The printf() and scanf() Functions
What is printf and scanf in C? The printf() and scanf() functions are used for input and output in C language. Both functions are inbuilt library functions defined in stdio.h.
Writing "Hello, World" in C++
How do you write hello, world in c++? Create an empty console project named "HelloWorld." Use that name for the cpp source file as well. In the empty "HelloWorld.cpp" file, enter the following code:
#include <iostream>
int main() {
std::cout << "Hello, World!";
return 0;
}
