My doubt : String constant related doubt

Question

"If a string constant is given then through by a pointer we can access the characters but we can't change any of the characters"

Can someone please expain this?

Answer 1

String in C is defined as constant and it gets  memory in the data section of the code. Whenever you execute your program ,then the string is taken as a constant value and any modification to it throws an error.

String can be defined as an array of character, so you access individual character using pointer.
