C++ programming language part: 41 Standard String-Handling function
Standard String-Handling function
strcpy()
The strcpy()
function is used to copy the content of second string to first string. second
string must be a pointer to a null-terminated string. The strcpu() function returns a pointer to the end of first string.
Program 30
{
char a1[10],a2[10];
cout<<"Type a string
"<
cin>>a1;
cout<<"Type another string
"<
cin>>a2;
cout<
}
strcat()
The strcat()
function work the same as the strcpy()
function except that the characters from the second string are copied onto the
end of the first string.
Program 31
{ char a1[10],a2[10];
char x[20];
cout<<"Type a string
"<
cin>>a1;
cout<<"Type another string
"<
cin>>a2;
//x=strcat(a1,a2);
cout<
//cout<
Note:Mind it that the second string would be the same.You can
do also cout<
Exercise: Make
some program by using strcat(a1,"Nova")
or (strcpy(a1, "Hello")
strcmp()
The strcmp()
function compares two string and returnes an integer value, what is the ASCII
value.
Program 32
{ char
a1[10],a2[10];
int x;
cout<<"Type a string
"<
cin>>a1;
cout<<"Type another string
"<
cin>>a2;
x=strcmp(a1,a2);
cout<
strlen()
This function returns the number of characters in the
string passed to it. The length does not include the NULL character.
Program 33
{ char
a1[10],a2[10];
int len1;
int len2;
int sum;
cout<<"Type a string
"<
cin>>a1;
cout<<"Type another string
"<
cin>>a2;
len1=strlen(a1);
len2=strlen(a2);
sum=len1+len2;
char *p;
p=a1+len1-2;
// last two letters
cout<<"The length of two string is
"<
cout<< "The last two letters of
furst string is "<
Note: The file string.h should be included as a header
file
