String Functions In C++

String Functions In C++

It has 7 types

1. string concatenation

2. string comparision

3. string copy

4. string length

5. string reverse

5. string upper

6. string lower

String concatenation

#include<iostream.h>

#include<conioh.>

#include<string.h>

void main()

{

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string 1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

strcat(string1,string2);

cout<<"The given string1 is:"<<string1<<endl;

getch();

}

String compare

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

int x;

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

x=strcmp(string1,string2);

if(x==0)

cout<<"The given name is same"<<endl;

else

cout<<"The given name is different"<<endl;

getch();

}

String copy

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

int x;

char string1[20];

char string2[20];

clrscr();

cout<<"Enter the string1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

strcpy(string1,string2);

cout<<"The given string1 is:"<<string1<<endl;

cout<<"The given string2 is:"<<string2<<endl;

getch();

}

String length

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

int n1,n2;

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string 1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

n1=strlen(string1);

n2=strlen(string2);

cout<<"The given length of the string1 is"<<n1<<endl;

cout<<"The given length of the string2 is"<<n2<<endl;

getch();

}

String without int

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

cout<<"The given length of string1 is "<<strlen(string1)<<endl;

cout<<"The given length of string2 is"<<strlen(string2)<<endl;

getch();

}

String reverse

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string1 is:"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>string2;

strrev(string1);

strrev(string2);

cout<<"The given reverse of the string1 is "<<string1<<endl;

cout<<"The given reverse of the string2 is"<<string2<<endl;

getch();

}

String upper, lower

#include<iostream.h>

#include<conio.h>

#include<string.h>

void main()

{

char string1 [20];

char string2 [20];

clrscr();

cout<<"Enter the string1 is"<<endl;

cin>>string1;

cout<<"Enter the string2 is:"<<endl;

cin>>String2;

strupr(string1);

strlwr(string2);

cout<<"The given reverse of the string1 is<<string1<<endl;

cout<<"The given reverse of the string2 is<<string2<<endl;

getch();

}
