5. Output format

There are three output formats that are normally used

        1.%md

It is possible to make int-types with less than m bits to rightaligned output, where the high digit is filled with a space and remains unchanged if itself exceeds m digits

int a = 123;




printf("%5d\n",a);



 



// Output



  123

        2.%0md

Unlike md, when the variable is less than m, it is preceded by enough zeros instead of spaces.

int a = 123;




printf("%5d\n",a);



 



// Output



00123

        3.%.mf

It is possible to have floating point numbers retain m bits of output, taking the principle of rounding up to five into two

 




double d1 = 12.3456;




printf("%.3f,d1)




// Output



12.346
