It returns a pointer to s1 where the resulting concatenated string resides. 29, May 20. The declaration and definition of the string using an array of … The string.h header classifies one variable type, one macro, and various functions to manipulate arrays of characters within your program. The syntax for the strcat function in the C Language is: char *strcat(char *s1, const char *s2); Parameters or Arguments s1 It is also often used to format strings into specific formats. 16, Oct 19. String.Format() method has 8 overloaded formats to provide options to format … ASIDE - STRING REFRESHER When working with strings in C, remember - strings are no more than arrays of ASCII-encoded characters ending with a terminating null byte (\0). And lastly the return 0; statement is used to return an integer type value back to main(). Store it in some variable say str1 and str2. You concatenate strings by using the + operator. (String Concatenation) In the C Programming Language, the strcat function appends a copy of the string pointed to by s2 to the end of the string pointed to by s1. Methods vs. This C program is used to concatenate strings by using strcat() function. Keep the order as first come first and second comes second after concatenation. Different methods to reverse a string in C/C++ . Next, it will use For Loop to iterate each character present in that arrays, and joins them (or concatenate them). So first of all, you have to include the stdio header file using the "include" preceding # which tells that the header file needs to be process before compilation, hence named preprocessor directive. String.Format() method formats strings in a desired format by inserting objects and variables with specified space and alignments into another strings and literals. The strcat function joins the copy of string pointed by string_2 to the end of the string pointed by string_1 and it returns a pointer to string_1. Using "" adds that automatically, but otherwise you have to add it yourself, and all string functions depend on that 0 being there. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. Thus, serving the purpose of string concatenation.

The inside the main() function, you have to take two character arrays name as a[] and b[] having 100 consecutive memory location.
