What is the difference between char a[] = "string"; and
char *p = "string"; ?

Answer / dharanidhar
P is a pointer which is constant. So, the values in this
array cannot be modified.
characters within a[] can be changed by accessing
like a[1] = '2',....

Answer / parmjeet kumar
char a[] will alocate the momery size of " string" word in
other hand char *p will alocate the memory size of one
character... or we can not move the data from one location
to another location but with pointer we can do it...

Answer / ashish
here a is an array and is a char const * data type.
hence u cannot change value of a but u can change the value
which a points to.
p on the other hand is a const char * data type.
hence value of p an be changed but the value p points to
cannot be changed.
i dont know the answer!!! :P

Answer / aravind
hi im answering as far as i know , pls say ur feedback,,,(+_+)
Array:
for char array char a[]; no such array size is accepted by
the compiler. That is , it requires a fixed size for the
array like: char a[20];
in this case the number of strings / characters it can hold
is only upto 20 while if it exceeds , the input strings get
truncated. [STATIC MEMORY ALLOCATION AND TRAVERSAL WITHIN
BOUNDS]
Pointer:
Whereas in case of pointers it is of DYNAMIC MEMORY type and
infinite storage when compared to Array. and predefinition ,
truncation are absent.
Also TRAVERSAL is easy.

Here is a good puzzle: how do you write a program which produces its own source code as output?
program for following output using for loop? 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5
a=10;b= 5;c=3;d=3; if(a printf(%d %d %d %d a,b,c,d) else printf("%d %d %d %d a,b,c,d);
please give me answer with details #include<stdio.h> main() { int i=1; i=(++i)*(++i)*(++i); printf("%d",i); getch(); }
Explain this code. #include <stdio.h> void f1(int *k) { *k = *k + 10; } main ( ){ int i; i = 0; printf (" The value of i before call %d \n", i); f1 (&i); printf (" The value of i after call %d \n", i); }
what are two kinds of java
wats the diference btwen constant pointer and pointer to a constant.pls give examples.
What is meant by inheritance?
enum DAY { sunday, monday, tuesday }; enum EDAYS { friday, saturday, sunday }; void main() { int i =0; if( i == sunday) { printf("%d",i); } } what would be the output?
please give code for this 1 2 4 7 11 16
Reverse the part of the number which is present from position i to j. Print the new number.[without using the array] eg: num=789876 i=2 j=5 778986
the portion of a computer program within which the definition of the variable remains unchanged a) mode b) module c) scope d) none
