Swift sprintf

sprintf(spec, variable list) will generate a string based on the specified format.

Example: string s = sprintf("\t%s\n", "hello");

Format specifiers

%%	% sign
%M	Filename output (waits for close)
%p	Format variable according to an internal format
%b	Boolean output
%f	Float output
%i	int output
%s	String output
%k	Variable sKipped, no output
%q	Array output

strcat

strcat(a,b,c,d,. . . ) will return a string containing all of the strings passed as parameters joined into a single string. There may be any number of parameters.

The + operator concatenates two strings: strcat(a,b) is the same as a + b.
