Discover What is Fibonacci series in C, a technique that involves calling a function within itself to solve the problem. Even know how to implement using different methods.
Main function –This function marks the start of any C program. It is a preset function that is first executed when a program is run. The main function may call other functions to execute specific tasks. Example: int main(void) { // code to be executed return 0; } ...
Memory allocation is performed using themalloc()function in C Language. This method gives back a reference to a memory block with the specified size. The pointer value is used to access the allocated memory block. Once the memory is not required, it needs to be freed using thefree()function...
EOF, also known asEnd-of-File, is a common term used in the C programming language. It is used to signify the end of a file or program when a certain criterion is met. TheEOFmarker is the indicator placed at the end of the file that informs the C program that there is nothing els...
size_t c = sizeof(7); size_t d = sizeof(3.234); size_t e = sizeof a; The result of the sizeof operator is of a type called size_t, which is defined in the header file <stddef.h>. size_t is an unsigned integer type, perhaps identical to unsigned int or unsigned long int...

Short for enumeration, an enumvariable typecan be found in C (ANSI, not the original K&R), C++ andC#. The idea is that instead of using anintto represent a set of values, a type with a restricted set of values is used instead. ...
