Putting Strings Together

Putting Strings Together

We cannot assign one string to another directly We cannot join two strings together by the simple arithmetic addition.
       string3 = string1+string2;
       string3 = string1+'hello";   are not valid.
The characters from string1 and string2 should be copied into the string3 one after the other.The size of string3 should be large enough to hold the total characters.The process of combining two strings together is called concatenation.'C' does not permit the comparison of two strings directly.
               if(name1==name2)
               if(name==''ABC") are not valid.
It is therefore necessary to compare the two strings to be tested , character by character.
The comparison is done until there is a mismatch or one of the string terminates into a null character, whichever occurs first.
