A pointer is a constant or variable that contains an address of another variable of same type and in future, same address can be used to access the variable. Syntax for pointer declaration: So, using above syntax we can declare any type (built-in or derived) of pointer variable. In following figure, three built-in type of pointer variable has been created …
When a process invokes/calls fork() function, a new process is created which has the same address space. As the address space is copied => PC (program counter) will also has the same value as old process has. That means the newly created process (also called as child process) will start executing from the instruction, parent process is currently executing => …
A 2-D array can be logically think of array of arrays as shown below: Let’s have a program to understand 2-D array better: output a=0x7ffd8da57dc0 &a=0x7ffd8da57dc0 a[0]=0x7ffd8da57dc0 &a[0][0]=0x7ffd8da57dc0 a[1]=0x7ffd8da57dc8 &a[1][0]=0x7ffd8da57dc8 a[2]=0x7ffd8da57dd0 &a[2][0]=0x7ffd8da57dd0 Note: these values may vary, as the allocated memory location may change every time when a program is executed. The memory view of above program can be analyzed …
An array can be defined as finite collection of homogeneous data, stored in contiguous memory locations. Where, finite: means the number of elements to be stored in array has to be predefined finite number. homogeneous: all the elements of the array should be of same type (i.e. int, char, float etc.). contiguous: all the elements of the array should be …
Data communication is the process of transmitting data from a source to destination. The following power point presentation give some overview to this domain. Credit: some random internet sources and the book – data communication by Frouzan
