int main()
{
	float g=123.456789;
	printf("\n %.1f",g);
	printf("\n %.2f",g);
        printf("\n %.3f",g);
	printf("\n %.4f",g);
	getch();
	
}

This program demonstrates the use of precision specifiers.

The program initializes a float variable g with a value of 123.456789. Then it uses the printf function to display the value of g with different levels of precision.

The precision is specified by adding a dot . and a number after the field width in the format string. For example, %.1f specifies one digit of precision after the decimal point.

The program displays the value of g with precision of 1, 2, 3, and 4 decimal places. The output will be:

123.5
123.46
123.457
123.4568

The value is rounded to the specified number of decimal places.

Thanks
