TCS Programming Code in Fibonaaci series Interview Questions

#include <stdio.h>

int main(int argc, char *argv[])

{

int n, first = 0, second = 1, next, c;

n = atol(argv[1]);

printf(“First %d terms of Fibonacci series are :-\n”,n);

for ( c = 0 ; c < n ; c++ )

{

if ( c <= 1 )

next = c;

else

{

next = first + second;

first = second;

second = next;

}

printf(“%d\n”,next);

}

return 0;

}

TCS Interview Quesions on the output of this C code?

#include <stdio.h>

void main()

{

int k = 5;

int *p = &k;

int **m = &p;

printf(“%d%d%d\n”, k, *p, **p);

}

a) 5 5 5

b) 5 5 junk

c) 5 junk junk

d) Compile time error

Given the below statements about C programming language

1) main() function should always be the first function present in a C program file

2) all the elements of aaunion share their memory location

3) A void pointer can hold athe ddress of any type and can be typcasted to any type

4) A static variable hold random junk value if it is not initialised

TCS Interview Questions: Which of the above are correct statements?

A) 2,3

B) 1,2

C) 1,2,3

D) 1,2,3,4

TCS Interview Questions: If a function is defined as static, it means

A) The value returned by the function does not change

B) all the variable declared inside the function automatically will be assigned initial value of zero

C) It should be called only within the same source code / program file.

D) None of the other choices as it is wrong to add static prefix to a function

TCS Interview Questions to Print all Command Line argument integers

// Program to print all value of
// command line argument
// once we get the value from command
// line we can use them to solve our problem.
#include <stdio.h> // this is used to print the result using printf
#include <stdlib.h> // this is used for function atoi() for converting string into int

// argc tells the number of arguments
provided+1 +1 for file.exe
// char *argv[] is used to store the command line
arguments in the pointer to char array i.e string format
int main(int argc, char *argv[])
{
// means only one argument exist that is file.exe
if (argc == 1) {
printf(“No command line argument exist Please provide them first \n”);
return 0;
} else {
int i;
// actual arguments starts from index 1 to (argc-1)
for (i = 1; i < argc; i++) {
int value = atoi(argv[i]);
// print value using stdio.h library’s printf() function
printf(“%d\n”, value);
}
return 0; } }

Output Answer: 24 and 50
