C did not have them as such the data type string, because of which we had to form a character array to form a 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 the strcat function of "string.h", to dot it without using the library function, see another program below. Insert one string into another.
