The uppercase() method of stream manipulators in C++ is used to set the uppercase format flag for the specified str stream. This flag makes the output operations to use capital letters instead of lowercase letters.
Syntax:
ios_base& uppercase (ios_base& str)
Parameters: This method accepts str as a parameter which is the stream for which the format flag is affected.
Return Value: This method returns the stream str with uppercase format flag set.
Example 1:
// C++ code to demonstrate // the working of uppercase() function #include <iostream> #include <sstream> using namespace std;
int main()
{ // Initializing the int
int n = 20;
// Using uppercase()
cout << "uppercase flag: "
<< showbase << oct
<< uppercase
<< n << endl;
return 0;
} |
Output:
uppercase flag: 024
Example 2:
// C++ code to demonstrate // the working of uppercase() function #include <iostream> using namespace std;
int main()
{ // Initializing the int
int n = 20;
// Using uppercase()
cout << "uppercase flag: "
<< showbase << hex
<< uppercase
<< n << endl;
return 0;
} |
Output:
uppercase flag: 0X14
