how to use printf with microseconds c++
To use printf
with microseconds in C++, you can follow these steps:
- Include the necessary header file: To use the
printf
function, you need to include the<cstdio>
header file in your C++ program. This header file provides the functionality for formatted input/output operations.
#include <cstdio>
- Use the
printf
function: Theprintf
function allows you to format and print output to the console. To print microseconds, you can use the%lld
format specifier for along long int
data type.
long long int microseconds = 123456789;
printf("Microseconds: %lld\n", microseconds);
In this example, the value 123456789
is stored in the microseconds
variable. The %lld
format specifier is used to print the value as a long long int
.
- Run the program: Compile and run your C++ program to see the output. The
printf
function will print the value ofmicroseconds
to the console.
Microseconds: 123456789
The output will display the value of microseconds
as 123456789
, indicating that the printf
function successfully printed the value with microseconds.
That's how you can use printf
with microseconds in C++.
