Question

Using C:

Implement the function ranges that takes no input and prints the ranges (i.e., the minimum and maximum legal values) of the types char, short, int, long, and long long, both signed and unsigned. You should do this by printing appropriate constants defined in the header file /usr/include/limits.h (this is why hw1.c starts with #include <limits.h>). This should print something like:

signed char
minimum value: -128
maximum value: 127

unsigned char
minimum value: 0
maximum value: 255

signed short
minimum value: -32768
maximum value: 32767

Void ranges() {

//IMPLEMENT THIS

}

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

VERY IMPORTANT NOTES: These limits may vary depend on the version of the compiler you are using. LLONG_MIN, LLONG_MAX and ULLONG_MAX are introduced in compiler version C99, so old compilers may not support them. In some compilers int & short int have the same range, while in some other compilers, int and long types have the same range. Also, the definitions for format specifiers used in this code are below.

%d – int

%u – unsigned int

%ld – long int

%lu – unsigned long int

%lld – long long int

%llu – unsigned long long int

//CODE

#include<limits.h>

#include<stdio.h>

void ranges(){

              //char-signed

              printf("signed char\n");

              printf("minimum value: %d\n",SCHAR_MIN);

              printf("maximum value: %d\n",SCHAR_MAX);

             

              //char-unsigned

              printf("\nunsigned char\n");

              printf("minimum value: %d\n",0);

              printf("maximum value: %d\n",UCHAR_MAX);

             

              //short-signed

              printf("\nsigned short\n");

              printf("minimum value: %d\n",SHRT_MIN);

              printf("maximum value: %d\n",SHRT_MAX);

             

              //short-unsigned

              printf("\nunsigned short\n");

              printf("minimum value: %d\n",0);

              printf("maximum value: %d\n",USHRT_MAX);

             

              //int-signed

              printf("\nsigned int\n");

              printf("minimum value: %d\n",INT_MIN);

              printf("maximum value: %d\n",INT_MAX);

             

              //int-unsigned

              printf("\nunsigned int\n");

              printf("minimum value: %d\n",0);

              printf("maximum value: %u\n",UINT_MAX);

             

              //long-signed

              printf("\nsigned long\n");

              printf("minimum value: %ld\n",LONG_MIN);

              printf("maximum value: %ld\n",LONG_MAX);

             

              //long-unsigned

              printf("\nunsigned long\n");

              printf("minimum value: %lu\n",0l);

              printf("maximum value: %lu\n",ULONG_MAX);

             

              //long long-signed

              printf("\nsigned long long\n");

              printf("minimum value: %lld\n",LLONG_MIN);

              printf("maximum value: %lld\n",LLONG_MAX);

             

              //long long-unsigned

              printf("\nunsigned long long\n");

              printf("minimum value: %llu\n",0ll);

              printf("maximum value: %llu\n",ULLONG_MAX);

             

              //Note: LLONG_MIN,LLONG_MAX and ULLONG_MAX are introduced in compiler version C99

              //so old compilers may not support them.

}

int main(){

              ranges();

              return 0;
