Question

***The following is to be written in C:****

Modify the sizeof.c program (in the sizeof folder on github) and show the data range (min and max) in addition to the size of the data types in a nice table (print one line for each data type). Refer to section B11 in your textbook (page 257) for getting min and max values for each data type; use macros instead of number constants in your program.

****The following is the sizeof.c program that needs to be modified:****

****Section B11 the question asks to refer to:****

Answer 1

#include<stdio.h>
#include<limits.h>
#include<float.h>

int main()
{

printf(" Data type | size | Min | Max |\n");
printf("------------------------------------------\n");
char c;
printf(" char %lu %d %d \n",sizeof(c),SCHAR_MIN,SCHAR_MAX);

printf("------------------------------------------\n");
unsigned char uc;
printf("unsigned char %lu 0 %d \n",sizeof(uc),UCHAR_MAX);
printf("------------------------------------------\n");
short s;
printf(" short %lu %d %d \n",sizeof(s),SHRT_MIN,SHRT_MAX);
printf("------------------------------------------\n");
unsigned short us;
printf("unsigned short %lu 0 %d \n",sizeof(us),USHRT_MAX);
printf("------------------------------------------\n");
int i;
printf("int %lu %d %d \n",sizeof(i),INT_MIN,INT_MAX);
printf("------------------------------------------\n");
unsigned int ui;
printf("unsigned int %lu 0 %u \n",sizeof(ui),UINT_MAX);
printf("------------------------------------------\n");
long l;
printf("long %lu %ld %ld \n",sizeof(l),LONG_MIN,LONG_MAX);
printf("------------------------------------------\n");
unsigned long ul;
printf("unsigned long %lu 0 %lu \n",sizeof(ul),ULONG_MAX);
printf("------------------------------------------\n");
long long ll;
printf("long long %lu %ld %lld \n",sizeof(ll),LLONG_MIN,LLONG_MAX);
printf("------------------------------------------\n");
unsigned long ull;
printf("unsigned long long %lu 0 %llu \n",sizeof(ull),ULLONG_MAX);

printf("------------------------------------------\n");
float f;
printf("float %lu %f %f |\n",sizeof(f),FLT_MIN,FLT_MAX);
printf("------------------------------------------\n");
double d;
printf("double %lu %lf %lf |\n",sizeof(d),DBL_MIN,DBL_MAX);

}

output depends upon compilers:
