Where string is stored on Heap or Stack in java?
A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.A String is treated as an object, meaning there is an object on the heap.

Why does C forbid converting a string constant to 'char' ?
C forbids converting a string constant to 'char' because string constants are stored in read-only memory, and attempting to modify them through a 'char' pointer can lead to undefined behavior and potential program crashes.
Why pointer is used to reference a string of characters write C plus plus statements that display the text hello using pointer to a string notation?
We use a pointer to reference a string because a string is an array of characters where every element is a char (or a wchar_t if using UNICODE strings). Passing arrays by value would require the entire array to be copied, but passing a pointer variable to an array only copies the pointer, which is effectively the same as passing the array by reference. #include <iostream> int main() { char * psz = "hello"; // pointer to a null-terminated string. std::cout << psz; // pass the pointer (by value) to the insertion operator. return( 0 ); }
How do you write c program to accept a string from the console and count number of vowels constants digits tabs and blank spaces in a string?
Read the characters one at a time, and write an "if" for each of the cases. In each case, if the condition is fulfilled, increment the corresponding counter variable.

What is cputs function in computer c plus plus?
Nothing.The C language only recognizes a few keywords, like "for" and "if". Most of what's in a C program ... that doesn't reference routines in the C program itself ... are library calls, and cputs() is one of those. What it does is write its argument (which should be a pointer to a character string) to the console... console put string.
