Some Subex Technical Questions and programs to solve are:
void main()
{
enum bool{true,false};
if(true==(2==3)
printf(“..
else
printf(“..
}
void main()
{
printf(“%d”,(float)3/2);
}
void main()
{
int (*func)(const *char)=strlen;
printf(“%d”, func(“Hello”);
}
These are C language IT company coding, programming language technical / tech written test questions.
void main() {
char *s=”Hello World”;
printf(“%c”,s);
}
File fp,fs;
fp=fopen(“tc.dat”,”w”);
fs=fopen(“tc.dat”,”w”);
putch(‘A’,fp);
putch(‘B’,fs); What will happen?
What is the equivalent of a[i] Ans: *(a+i)
These are the Subex azure C language programs and questions related to pointers, operator overloading, file handling, etc.
int (*func)(int,int) is a pointer to a function with 2 integers as parameters and returning an integer value.
int *(*func)(int *,int *) is a pointer to a function with 2 integer pointers as parameters and returning a pointer to
an integer Which of a and b is true?
Ans: Both are true.
switch(float value) this is compiler error.
int a[5]={1,2,3,4,5};
int *p=a+1;
int *q=a+5;
int dif=q-p;
value of dif is 4 ( q-p is evalueated as q-p/sizeof int)
Switch(NULL)
ans: case 0: will be executed.
#define exp 5
printf(“%d”,exp++);
ans: compilation error lvalue required
strcat(str,str);
ans: compilation error
Pointers can be subtracted from each other, can be added, constant can be added or subtracted from pointer, but multipilcation with constant to pointer is not possible.
int(*ptr)[10] pointer to array of 10 integers.
