turbo-c

A question was asked in a multiple choice test: What will be the output of the following program: #include <stdio.h> int main(void) { int a = 10, b = 5, c = 2; printf("%d %d %d\n"); return 0; } and the choices were various permutations of 10, 5, and 2. For some reason, it works in Turbo C++, which we use in college. However, it doesn't when compiled with gcc (which gives a warning when -Wall is enabled) or clang (which has -Wformat enabled and gives a warning by default) or in Visual C++. The output is, as expected, garbage values. My guess is that it has something to do with the fact that

I have a piece of code in C given as follows : main() { int a=10, b; a>=5 ? b=100 : b=200 ; printf("%d" , b); } running the code on gcc compiler in unix generates the compile-time error as 'lvalue required as left operand of assignment' and points the error at b = 200 whereas in windows compiling using Turbo C gives 200 as output. Can anybody please explain what exactly is happening in this case ? In C the ternary operator is defined like logical-OR-expression ? expression : conditional-expression where conditional expression is defined like logical-OR-expression The assignment operator has a
