You have to use the printf() function for displaying the message - "Enter the first string" to the screen. As it is inbuild and predefined function it is mostly associated and defined in “string.h” header file. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. It is also often used to format strings into specific formats. Here stra1, stra2 already assigned with the string values by assigning. C++ Strings : String is a sequence of characters.

I am having trouble concatenating strings in C, without strcat library function. while loop; char array; if statement 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. Code: #include #include int main() { char stra1[] = "This is ", stra2[] = "programiz.com"; //concatenates stra1 and stra2 and resultant string is stored in str1. Then you have to define the main() function and it has been declared as an int as it is going to return an integer type value at the end of the program. Concatenation of two strings is simple copying a string to another.
