Please write comments if you find the above code incorrect, or find better ways to solve the same problem. 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. Output: Enter String 1: Journal Enter String 2: Dev Concatenated String: JournalDev 4. For concatenation we have not used the standard library function strcat(), instead we have written a logic to append the second string at the end of first string.

C program to concatenate two strings; for example, if the two input strings are "C programming" and " language" (note the space before language), then the output will be "C programming language." Keep the order as first come first and second comes second after concatenation. EXPLANATION OF STRING CONCATENATION WITHOUT USING PREDEFINED FUNCTION IN C PROGRAMMING. Get the two Strings to be concatenated. Similarly another printf for displaying the second message - "Enter the second string" and so the second string will also get fetched from the keyboard using gets() and stored in character array b[]. The strcat () function concatenated (join) two strings. Strings Concatenation in C The concatenation of strings is a process of combining two strings to form a single string.

C Program String Concatenation using strcat:input two strings. Then comes the use of strcat() which is abbreviated as string concatenation, and is having syntax as: char *strcat(dest, src), where 'dest' defines the destination array (here in this program 'a'), which should contain a string and should be larger for containing the concatenated resulting string. Then comes the use of strcat() which is abbreviated as string concatenation, and is having syntax as: char *strcat(dest, src), where 'dest' defines the destination array (here in this program 'a'), which should contain a string and should be larger for containing the concatenated resulting string. C strings must end in 0 byte, in other words '\0' character. And lastly the return 0; statement is used to return an integer type value back to main(). 16, Oct 19.
