Kaust Phd Scholarship - In c++, const is a keyword used to declare a variable as constant, meaning its value cannot be changed after it is initialized. The reason why it may point to a single char or the start of an array is an accident in c that we all have to live with. There is a reason but it's beyond the scope of the question. Also, compilers are required to. You cannot change the contents of the location (s) this pointer points to. If you do not need to modify the data, using const char text[] reduces the number of relocations in the object file, and requires fewer machine code instructions to access. The const keyword in c++ stands for constant. There are 3 confusing combinations which make us feel ambiguous, const char *, const * char, and const *char const, let’s eliminate the syntax confusion and understand the. It is used to declare variables, objects, pointers, function parameters, return values, and class methods as unchangeable. Const char* is a mutable pointer to an immutable character/string.

If you do not need to modify the data, using const char text[] reduces the number of relocations in the object file, and requires fewer machine code instructions to access. Also, compilers are required to. It helps protect important values from accidental. It is used to declare variables, objects, pointers, function parameters, return values, and class methods as unchangeable. Const char* is a mutable pointer to an immutable character/string. There is a reason but it's beyond the scope of the question. The reason why it may point to a single char or the start of an array is an accident in c that we all have to live with. Essentially the const char* erases the size part of the compile time type information. The const keyword in c++ stands for constant.
