In practice, I'd never write such a for loop in a program. Instead, I'd use the built-in strcpy() function. There are several library functions built into C for working with strings. (Their prototypes are in the string.h header file; we'll talk about header files in Section 3.2.)...

and in fact pointers to any type in C, it shouldn't come as too much of a surprise that we can have pointers to other pointers. If we're used to thinking about simple pointers, and to keeping clear in our minds the distinction betweenthe pointer itselfandwhat it points...
The practice just shown is common, but to use it you have to be absolutely sure the array contains a value equal to NULL. Otherwise, the loop causes a buffer overflow, proceeding until it happens to hit some value in memory that equals NULL, or causes a fatal error by exceeding the ...
An address of zero is not always valid for use in a program on most operating systems. We will discuss this in more detail in the section The Concept of Null. Note It is a good practice to initialize a pointer as soon as possible, as illustrated below: int num; int *pi; pi = &...
You had a glimpse of pointers in the last chapter and just a small hint at what you can use them for. Here, you'll delve a lot deeper into the subject of pointers and see what else you can do with them. I'll cover a lot of new concepts here, so you may need to repeat some ...
Based on the C♭-model, technical and educational support are factors that affect higher education teachers' use of technology in their courses (Sailer et al., 2021). Technical support means helping higher education teachers and students with hardware or software problems, whereas educational suppor...

However, as explained in the sectionOne-Dimensional Arrays, this is not the correct way of determining its size. In this case, we would be passing the value of 20 to the array. displayArray(arr, sizeof(arr)); It is a common practice to pass a size smaller than the actual number of...
