c - Please Explain Comma Operator in this Program -



c - Please Explain Comma Operator in this Program -

please explain me output of program:

int main() { int a,b,c,d; a=10; b=20; c=a,b; d=(a,b); printf("\nc= %d",c); printf("\nd= %d",d); }

the output getting is:

c= 10 d= 20

my uncertainty "," operator here? compiled , ran programme using code blocks.

the , operator evaluates series of expressions , returns value of last.

c=a,b same (c=a),b. why c 10

c=(a,b) assign result of a,b, 20, c.

as mike points out in comments, assignment (=) has higher precedence comma

c comma

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
