Latest Answer : #include#includevoid main(){ int a,i;clrscr();printf( " enter the number");scanf("%d",&a);for(i=a;i
main{int x=90;float *ptr;ptr=(float *)&x;*ptr=50.0;printf("%d",x);printf("%f",*pf);}Though the address of i & pf are same but the value which i get when i print x is a different integer
Latest Answer : It is always helpful to write valid code. Your example would not compile and the output would not be readable.1: int x = 90;2: float* ptr;3: ptr = (float*)&x;4: *ptr = 50.0f; ...
When dynamic allocation of memory is done by using malloc then how is the memory allocated in sequential or in some other format ?
We have a 2 arrays e.g. arr1[]={2,3,4,4,5,6,7} , arr2[]={1,2,2,4,6,8,8} . Assuming that both the arrays We have a 2 arrays e.g. arr1[]={2,3,4,4,5,6,7} , arr2[]={1,2,2,4,6,8,8} . Assuming that both the arrays are sorted , if we want to write a program to find common numbers present in both arrays , how do we do that ? Note that nested for loop has a complexity of n2 , hence avoid nested for loop.
