    Explain the meaning of “Segmentation violation”.



    Segmentation violation usually occurs at the time of a program’s attempt for accessing memory location, which is not allowed to access. The following code should create segmentation violation.
    main() {
    char *hello = “Hello World”;
    *hello = ‘h’;
    At the time of compiling the program, the string “hello world” is placed in the binary mark of the program which is read-only marked. When loading, the compiler places the string along with other constants in the read-only segment of the memory. While executing a variable *hello is set to point the character ‘h’ , is attempted to write the character ‘h’ into the memory, which cause the segmentation violation. And, compiler does not check for assigning read only locations at compile time.
