An expression is evaluated once and compared to 'constants'. In case of equality, the 'statements' that come after the 'constant' are processed. In switch 'statements' can only ordinary data types (ie, 'int', 'long', char, short, etc.) can be used. text/html 2013-02-16T13:55:59+02:00 https://code-reference.com/c/control_structures/while?rev=1361019359&do=diff while #include <stdio.h> /* including standard library */ //#include <windows.h> /* uncomment this for Windows */ while ( condition == true ) { do something until condition untrue } C Sourcecode Example #include <stdio.h> /* including standard library */ //#include <windows.h> /* uncomment this for Windows */ int main(void) { int i=0; while (i <= 10) { printf("%i\n",i); i++; } return 0; }
