GEOMETRIC - PLACEMENT PAPER (C PROGRAMMIN)

Hi Friends

1) Pointers (they may ask in i.w)

2) C++ (this is very very imp, based on this only I got job. one more thing is class, inheratence; polymorphism is sufficient)

3) you should prepare one fem project and tell them that as your own work (this will increase chance to 99%)

12) two trains are travelline at equilateral. train a is travelling in the direction of earths spin. other train b is travelling in opposite direction of earths spin. which trains wheels will wear first? and why? (ans train b .because of less centrifugal force.)

C questions:

what is the out put for following programms

1)main()

{

char a[2];

*a[0]=7;

*a[1]=5;

printf("%d", &a[1]-a)

ans:

ans may be 1.(illegal initialization)

2)

#include<stdio.h>

main(){

char a[]="hellow";

char *b="hellow";

char c[5]="hellow";

printf("%s %s %s ",a,b,c);

printf(" ",sizeof(a),sizeof(b),sizeof(c));

}

(ans is hellow,hellow,hellow

6,2,5 )

3)

#include<stdio.h>

main()

float value=10.00;

printf("%g %0.2g %0.4g %f",value,value,value,value)

}

(ans is 10,10,10,10.000000)

4)

#include<stdio.h>

void function1;

int i-value=100;

main()

{

i-value=50;

function1;

printf("i-value in the function=",i-value);

printf("i-value after the function=",i-value);

}

printf("i-value at the end of main=",i-value);

functioni()

i-value=25;

this is rough idea of the program

ans are

1)i-value in the function=25;

2)i-value after the function=50;

3)i-value at the end of the main=100;

5)

main()

{

funct(int n);

switch(n)

case1:

m=2;

break;

case2:

m=5;

break;

case3:
