Why we need to use # include < string.h >
# include < string.h >: String Functions. The string functions
are present in the string.h header file. Some string functions are given below:
strlen(S) It
gives the no. of characters including spaces present in a string S.
strcat(S1,
S2) It concatenates the string S2
onto the end of the string S1. The string S1 must have enough locations to hold
S2.
strcpy(S1, S2) It
copies character string S2 to string S1. The S1 must have enough storage
locations to hold S2.
Etc.
