Because strings in C are just arrays of characters (or simply a string of characters stored in sequential memory locations) terminated by a null character, the only way to compare them is to do it character by character. intstrcmp(constchar*s1,constchar*s2); ...
9 free(strings[i]); 10} 11free(strings); Double Pointers in Function Arguments Using double pointers as function arguments allows for direct modification of pointer addresses and dynamic memory allocation within functions. Modifying Pointer Addresses A function that modifies the address stored by a ...
It discusses questions: How to use arrays; How to declare and use multidimensional arrays; How to use pointers; the relationship between arrays and pointers; How dynamic memory allocation works in a Common Language Runtime (CLR) program; How to work with strings and arrays in C++/CLI programs...
Having seen pointer used with arrays, strings, and structures, you can easily understand the final use shown here. A function in C can return only one value. You can return a pointer to a structure that contains many values. But for some purposes (such as setting error codes), programmers...
There are several library functions built into C for working with strings. (Their prototypes are in the string.h header file; we'll talk about header files in Section 3.2.) Following are three.void strcpy(char *dst, char *src) Copies all the characters of src into dst, including the ...

Pointers and Text Strings Historically, text strings in C have been implemented as arrays of characters, with the last byte in the string being a zero, or the null character '\0'. Most C implementations come with a standard library of functions for manipulating strings. Many of the more com...
