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.
