Strings are widely used in C++ ,Sequence of characters: WE HAVE 2 WAYS TO CREATE STRINGS AND USE THEM: 1.BY CREATING A CHARACTER ARRAYS ,TREAT THEM AS STRING. 2.BY CREATING A STRING OBJECT
char str[50]="ruparani thupakula"
User input : char str[50] cin>>str;
but it is ineffecinet method cin is delimter means it doesnot consider space eg: rupa is good output: rupa //after space it skips
use get
cin.get(str,50); //50 is size
"\0 " TERMINATES SIZE RUPA\0RANI GIVES OUTPUT:RUPA 2.String str="rupa rani";//DMA also if string s='a' // gives error cant compatable to typecasting to char ***no size considered n in string obj user input: use *getline(cin,str);
STRINGS OPERATIONS:
1.ACCESSING
2.CONCATATION:(+,.append(),strcat()
1. STR1 = STR1+STR2
2.STR1.APPEND(STR2)
3.strcat(str1,str2)
3.COMPARISON
1.strcmp(str1,str2) //3 cases
***if str2>str1 returns pos val
str2<str1 returns neg val;
== return 0
2.COMPARE
str1.compare(str2)
3.RELATIONAL : ==, >=, <=
***str1==str2
Find char which occurs max in a string
