To understand all programs in this article, you should have the knowledge of the following topics: Arrays Multi-dimensional Arrays Pointers Array and Pointer Relation Call by Reference Dynamic Memory Allocation Array and Pointer Examples Calculate the average of array elements Find the largest element ...
There is a close relationship between arrays and pointers in the C language. When passed as a parameter to a function, an array name is treated as a pointer to the first element of the array, as shown in the following example: C++ Copy /* fragment */ extern void f1(char * p1); ...
A pointer is said to be constant pointer when the address its pointing to cannot be changed. Lets take an example : char ch, c; char *ptr = &ch ptr = &c In the above example we defined two characters (‘ch’ and ‘c’) and a character pointer ‘ptr’. First, the pointer ‘ptr...
In C language, it is difficult to use the pointer to access the two-dimensional array element. The reason is the addresses of two-dimensional array are many, pointers that can access the two-dimensional array element are many and complex. This paper analyzes the two-dimensional array address ...
What is NULL pointer and how it is defined? For a user-defined data type, what should be used typedef or #define? Is char string[5] = "Hello"; valid? Missing ampersand/address of (&) in scanf() (C language Error) Too few arguments to function (C language Error) ...
