Some strings are constants, others aren't; some constants are strings, other aren't. So these are unrelated things. Examples:
"text" -- constant string
123 -- constant number
char s[40] -- variable string
In C programming, a string doesn't have a specific return type as it's essentially an array of characters. So, if a function is returning a string, it should be declared to return a pointer to a char (char*), since a string in C is represented as an array of characters terminated by a null character ('\0').
Constants and abstract methods. That's it.
When printing text through a string, \t can be used to produce a horizontal tab. The same can also be used when parsing input.Within the C language source code, a tab is considered a white space and ignored outside string constants, provided that it does not break a keyword into two parts.
constants are values that does not chnage through out the program exceution..
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.
The plus operator between string constants allows string concatination: string a = "Hello, "; string b = "World!"; string c = a + b; The output of c would be: "Hello, World!".
in C: strstr, declared in string.h
ISO C forbids converting a string constant to 'char' in C because string constants are read-only and attempting to modify them through a 'char' pointer can lead to undefined behavior and potential program crashes.
Coding constants in c means writing the constants in a certain way that the c language understands.
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.

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.
