Interview Questions


First there is a tech interview and after succeeding this, second is a tech cum HR interview. tell abt Urself. some C pgms are given and find their output.

1. main(){
char *p="Huawei";
printf("%s\n",p);
*p++;
printf(%s\n",p);
}

2. main(){
int x=5,y=7,z;
z = x++ + y++;
printf("%d\n",z);
z = ++x + ++y;
printf("%d\n",z);
}

3. main(){
int *p;
p=(int *)malloc(sizeof(int)*20);
memset(p,0,20) or memset(p,20,0) (i don't remember which one)
then some code, i don't remember
}

4. main(){
int x=4;
printf("%d\t%d\t%d",x,x>>2,x<<2);
}
