A pointer variable is a variable that may contain the address of another variable or any valid address in the memory.
pointervariable is a variable that can hold the address of variable and it is act as a array and adavantage of pointer varialble is to change the values in the prgroam in anywhere for example programvoid main(){int a=10,b=20 ...
Pointer variable are initialized by one of the following two waysØ Static memory allocation
Hope this may be the possible answer.#include#define MAX 5int main(){ int p[] = {1,2,3,4,5};//Static initialization int *q = NULL; int i; for(i=0;i
For accessing a VSAM cluster sequentially, STARTBR, READNEXT, ENDBR commands are used. Suppose the VSAM cluster is sorted on the basis of a field (lets say age) and using STARTBR pointer is positioned on the record with name 'brijesh'. By using READNEXT that record is read. Now if i again use READNEXT, next record will be read(which could be the record with name other than 'brijesh'). If I want to read the next record with the same name (i.e. brijesh), whether RESETBR will be
