1. Intermediate C Code Analysis Examples 1.1. Pointer Size and String Length Understand how a character pointer that points to a string literal behaves. Confirm that sizeof and strlen calculate values using different criteria . #include <stdio.h> #include <string.h> int main ( void ) { char * text = " 0123456789 " ; size_t result = sizeof (text) + strlen (text); printf ( "%zu\n" , result); return 0 ; } char *text is not an array that stores the string contents; it is a pointer that stores the starting address of a string literal. sizeof(text) is the size of the pointer variable itself, which is different from the length of the string it points to. strlen(text) counts the number of characters from the location the pointer references until it reaches '\0' . The size of a pointer can vary depending on the execution environment, and this explanation uses a 64-bit environment as its basis. 1.2. Poi...

1. Function Arguments in C Programming languages pass function arguments using either Call by Value or Call by Reference .  However, in C, function arguments are always passed by Call by Value .  In other words, the value passed to a function is a  copy , so the function cannot directly access the original variable. For this reason, C achieves a Call by Reference effect by using pointers to pass a variable's address as a value. 1.1. Function Argument Passing Methods Method What is passed Can change original Call by value The variable's value No Call by reference The variable's  address Yes 1.1.1. Call by Value Call by Value is a method that  passes a copy of the value to the function . Therefore, even if the value is changed inside the function, the original variable is not affected. 1.1.2. Call by Reference Call by Reference is a method that uses a pointer to...
