I was going through a pre written program where I find sprintf command.

if(IFROOT){
str1="bicoted; diameter(d):;
str2=dyn_sprint(", distance=" GFORM, diskratio);
}

here, str1 and str2 are initialized as strings, GFORM is defined as "%.10g" and diskratio is a variable. IFROOT is a flag

please help me to understand how str2=dyn_sprint(", distance=" GFORM, diskratio) is working

There's no `sprintf()` in that snippet of code... And what is this `dyn_sprint()` function? – Shawn Mar 27 '21 at 23:30
to be clear, `GFORM` is "defined" that way, as in, using `#define`? Do you know what happens in C when you put two string literals next to each other? – Karl Knechtel Mar 27 '21 at 23:30
What is "string nam"? – MikeCAT Mar 27 '21 at 23:32
@Shawn this dyn_sprintf() acts as sprintf having dynamic memory alocation – Atrayee Hazra Mar 28 '21 at 08:32
@ Karl Knechtel Yes GFORM is defined by #define. this is used to print the value upto 10decimal points I have no idea about the second question you have asked – Atrayee Hazra Mar 28 '21 at 08:34
@MikeCAT string name is written at the starting, they are str1 and str2 – Atrayee Hazra Mar 28 '21 at 08:36
