#include The preprocessor assumes, it is a standard library header and looks in the system folders first where the compiler has been installed. If instead a programmer defines a function by himself and place the .h file in the current working directory, he would use (note the double quotes) #include "stdio.h"
A pointer to an array is a pointer that points to the whole array instead of the first element of the array. It considers the whole array as a single unit instead of it being a collection of given elements. Consider the following example: [GFGTABS] C #include int main() { int arr[5] =

Predict the output of following C programs. Question 1 #include int main() { int arr[] = {}; printf("%d", sizeof(arr)); return 0; } Output: 0 C (or C++) allows arrays of size 0. When an array is declared with empty initialization list, size of the array becomes 0. Question
Both the stack and heap memory segments during execution. Here's a breakdown: Stack: Function arguments (argc, argv): These arguments are passed to the main function and stored on the stack. Local variables: Variables declared within the main function, including input, ch, lCnt, and bCnt, reside on the stack. Return address: When the main function calls a function like fopen or printf, the ...
