c - Taking user input in switch case -


can take input in switch case ? in here if run code, asks value of 'a' returns area 0. if define value of 'a' while declaring or anywhere outside of switch case, returns correct value.

double a, area; switch(ch) {     case 1: printf("equilateral triangle \n");             printf("value of side \n");             scanf("%f",&a);             area= 0.433*a*a;             printf("\n %f", area);             break;      default : break;  }

yes can. getting wrong result because using wrong specifier double. use %lf instead (in scanf).

see running code here.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
