Doubt in using % symbol under sprintf

Hi all,

I got a requirement of changing the display string in one of the application. It is something like changing "90 percentage CPU" to "90% CPU". First, i did the fix in one of the printf by doing

printf("%d\% CPU",per);

Then, i need the same changes under sprintf so i tried

sprintf(str,"\%%s","CPU");

But, when i tried to print the "str" i am getting the result as %s. So, i searched and found in some forum they suggested to use double % symbol like the following

sprintf(str,"%%%s","CPU");

With this change it is correctly printing %CPU. Can someon explain me how this intertpretation works under sprintf?

"\%" is wrong. It works here because it's escaped to "%", and since there is no valid character after the "%" printf will be sweet enough just to display %.
The solution is, as suggested, to replace all instances where you actually want to display "%" with "%%".

EVOEx,

Thanks for the clarification.
