sizeof(int)is 4 bytes. If there is not enough memory available, the malloc function returns the address zero to indicate the error (another name for zero is NULL and you will see it used throughout C code). Otherwise malloc proceeds....
Type this program into a file and save it as add.c. Compile it with the line gcc add.c -o add and then run it by typing add (or ./add). You will see the line "5 + 7 = 12" as output. Here is an explanation of the different lines in this program: The line int a, b, ...
A string constant is a sequence of characters enclosed in double quotes. So “a” is not the same as „a‟. The characters comprising the string constant are stored in successive memory locations. When a string constant is encountered in a C program, the compiler records the address of ...
As seen, the higher programming languages such as C enable you to solve this problem easily by writing four functions to be executed cyclically and over and over again. This book describes a very concrete application of C programming language, i.e. C language used for themikroC PRO for PIC...
