Aim: To implement a program for following string operations:
Code:

String substring(int ind, int len);
char charAt(int ind);
int indexOf(char ch);
String reverse();
void display();
};
void String::display()
cout< } void String::getdata() { gets(str); } String::String() { strcpy(str,""); } int String::length1() { int l; l=strlen(str); return (l); } void String::concat(String s) { strcat(str,s.str); } String String::substring(int ind, int len) { int l,x,m; char su[50]; String sub; strcpy(sub.str,""); for(x=ind,m=0;x<=len+1;x++,m++) { su[m]=str[x]; } su[m]='\0'; strcpy(sub.str,su); return (sub); } char String::charAt(int ind) { char c=' '; int l=strlen(str); if(ind>l) cout<<"Position out of Bounds"; else c=str[ind]; return (c); } int String::indexOf(char ch) { int x=1; while(str[x]!=ch && str[x]!='\0') x++; if(str[x]!=ch) return (-1); else return (x); } String String::reverse() { String s; strcpy(s.str,str); strrev(s.str); return (s); } void main() { clrscr(); String s1,s2,s3,s4; cout<<"Enter string 1:"; s1.getdata(); cout<<"\n\nEnter string 2:"; s2.getdata(); char ch='o'; int l=s1.length1(); cout<<"\n\nLength of string: '"; s1.display(); cout<<" 'is "< s1.concat(s2); cout<<"\n\nAfter concatenation:"; s1.display(); int ind=2, len=4; cout<<"\n\nStart Index="< s3.display(); char c=s1.charAt(ind+4); cout<<"\n\nCharacter at Index: "< int i=s1.indexOf(ch); cout<<"\n\nIndex of '"< s4=s1.reverse(); cout<<"\n\nReverse of \n\t'"; s1.display(); cout<<"'\n\t\tis \n\t"; s4.display(); getch(); } Output: Enter string 1: Ankit Goyal is Enter string 2: a student of VESIT.
