Why does int has the same range as short?
The int is a data type in c, c++ or java, It can divided in to two parts that is short and long. Int short if of same size as int (2).

How do you write c plus plus program to display size of the each data type?
The core if it would contain lines like these: printf ("sizeof (char)=%d\n" "sizeof (short)=%d\n" "sizeof (int)=%d\n" "sizeof (long)=%d\n" "sizeof (long long)=%d\n" "sizeof (size_t)=%d\n" "sizeof (void *)=%d\n" "sizeof (ptrdiff_t)=%d\n" "sizeof (va_list)=%d\n" "sizeof (intptr_t)=%d\n" , (int)sizeof (char) , (int)sizeof (short) , (int)sizeof (int) , (int)sizeof (long) , (int)sizeof (long long) , (int)sizeof (size_t) , (int)sizeof (void *) , (int)sizeof (ptrdiff_t) , (int)sizeof (va_list) , (int)sizeof (intptr_t) );
Is it true that the largest size for integer types is long int?
It is 'long long int' meaning 64 bit (8 byte).

What is the maximum size of int what happes when we cross that limit?
The maximum size of INT is 1. If you go over then it will be an error.
Write a program that sort any array of integers using pointers?
#include<iostream> void insertion_sort(int* a,int len) { for(int i=1; i<len; ++i) { int* hole=a+i; int* prev=hole-1; int cur=*hole; while(hole!=a && cur<*(prev)) { *(hole)=*(prev); --hole, --prev; } *hole=cur; } } void print_array(int* a,int len) { for(int i=0; i<len; ++i) std::cout<<a[i]<<" "; std::cout<<std::endl; } int main() { int a[]={9,1,8,3,7,2,5,4,6}; int size=sizeof(a)/sizeof(a[0]); std::cout<<"Before:\t"; print_array(a,size); insertion_sort(a,size); std::cout<<"After:\t"; print_array(a,size); return(0); }
Short int and long integers have how many bytes in C programming?
It depends on the programming language, the compiler, and the machine architecture. In C, the size of short int and int is not mandated by the language. Often, on 32-bit machines, 'int' will be 32-bit, while 'short int' may be 16-bit. But the only thing the language promises is that short int will be no larger than int.
What is the size of an identifier declared as integer in C?
int myvar; printf ("size of myvar is %d\n", (int)sizeof (myvar));
In c language size of data type int?
printf ("sizeof (int) is %d bytes", (int)sizeof (int)); Most likely it will be 2 or 4.
What is a implementation on n numbers of term in bubble sorting?
void bubblesort (int* array, int size) { if (!array size<2) return; int last_swap = size; while (last_swap>0) { int n=last_swap; for (int i=1; i<last_swap; ++i) { if (array[i]<array[i-1]) { array[i]^=array[i-1]^=array[i]^=array[i-1]; n=i; } last_swap = n; } }
