String Concatenate Without Using Library Function
String concatenation in c. The strcat function concatenated join two strings. Use strcat to concatenate two strings. If not you may get unexpected output. No run time concatenation occurs. Syntax of string interpolation starts with a symbol and code variables are within a bracket. The syntax for the strcat function in the c language is.
Strcat function 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 s1it returns a pointer to s1 where the resulting concatenated string resides. Therefore you cant directly concatenate them with other strings. Concatenation is the process of appending one string to the end of another string. There is no string concatenation operator in c.

It required header file stringh in string concatenate functions append one string to the end of the other 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 to concatenate the strings we use strcat function of stringh. Its important to note that the length of s1 should be sufficient to hold the string after concatenation.

A string in c is just a pointer to an array of char that is terminated by the first null character.

This is called concatenation. Programming is awesome here two strings s1 and s2 and concatenated and the result is stored in s1.
