Get the maximum value of a variable in C

Question

Is there a function in C that returns the maximum value of a variable like this (I will name the function \"maxvalue\" in example below)?

int a;
printf(\"%d\", m         


        

Answer 1

Could easily be done using ANSI C 89:

    #include
    #include

int main(void) {

printf("Max value of char: %d\n", CHAR_MAX);
printf("Min value of char: %d\n", CHAR_MIN);

printf("Max value of short: %d\n", SHRT_MAX);
printf("Min value of short: %d\n", SHRT_MIN);

printf("Max value of int: %d\n", INT_MAX);
printf("Min value of int: %d\n", INT_MIN);

printf("\n\n");
return 0;
}

Notice that you can include float.h and then use:

printf("Max value of Double: %d\n", DBL_MAX);

Though, it is less recommended.

Good luck, Ron
