Hallo,
I have this this example, but is this usefull in practical use?
Normaly I would work with IF or CASE, but this version can only answer 0 or 1.
But can I use it an put the result in a variable or something with this system?
Orf write different text statements?
Code:#include <stdio.h> #include <conio.h> int main(void){ int temper = 20; printf("Ist kleiner als 23°C %d\n", temper < 23); printf("Ist größer als 23°C %d\n", temper > 23); return 0; }

HM, ok, this doesn't work
I hoped it is like an IF oder Case
But why is always C=0?Code:c=5 == 8 > 6; printf("C ist %d\n", c);
The result is always 0?! Why not 99?Code:int c=99; c=5 == 6 > 1; printf("C ist %d\n", c);

Comarison operations yield an int with 0 representing logical false, and 1 (or any other value) representing logical true. You have to specify string literals that you conditionally pass to printf, along with the %s format specifier for a string. Like
I used inlined ternary operators here. You could also use if-else or switch-case to assign the string to a variable first.Code:#include <stdio.h> int main(void) { static const char eq[] = "gleich"; static const char lt[] = "kleiner als"; static const char gt[] = "größer als"; int temper = 25; printf("Ist %s 23°C.\n", temper == 23 ? eq : (temper < 23 ? lt : gt)); }
