C++ Exercises: Check if a given string begins with 'abc' or 'xyz'
C++ Basic Algorithm: Exercise-74 with Solution
Write a C++ program to check if a given string begins with 'abc' or 'xyz'. If the string begins with 'abc' or 'xyz' return 'abc' or 'xyz' otherwise return the empty string.
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
string test(string s1)
{
if (s1.substr(0,3) == "abc")
{
return "abc";
}
else if (s1.substr(0,3) == "xyz")
{
return "xyz";
}
else
{
return "";
}
}
int main()
{
cout << test("abc") << endl;
cout << test("abcdef") << endl;
cout << test("C") << endl;
cout << test("xyz") << endl;
cout << test("xyzsder") << endl;
return 0;
}
Sample Output:
abc abc xyz xyz
