EASY TECH PAPER ON 31st DECEMBER 2007

Paper Pattern

1) printf("%d%x\n",ox2,12);

2) int a=10;
int b=20;
a=a^b;
b=a^b;
a=a^b;
printf("%d%d\n",a,b);

3)enum
{ELLIPSE,
TRIANGLE,
RECTANGLE,
SQUARE=100,
CIRCLE=5

printf{"%d%d%d%d\n",TRIANGLE-RECTANGLE,SQUARE*CIRCLE-RECTANGLE};

4) define the following...
a) pointer to a integer
b) pointer to a char
c) function pointer returning a pointer integer.

5) void a(void);
main()

a();

void a(void)

char a="HELLOW";
char *b="HELLOW";
char c[10]="HELLOW";
printf("%s%s%s\n",a,b,c);
printf("%d%d%d\n",sizeof(a),sizeof(b),sizeof(c)));

6) int a=15;
int b=16;
printf("%d %d \n",a&b,a/b); (bitwise operators)

7) int a[5],*p;
for(p=a;p<&a[5];p++)

*p=p-a;
printf("%d\n",*p);

8) sscanf("xyz abc ABC 345" "% *[a-z A-Z]lf",&a);
printf("lf",a);

9) Not clear
fprintf(- - - - -

10) main()

int i=10;
printf("%d",i);

int i=20;
printf("%d",i);

printf("%d",i);

11)struct class

int i;
float a;
string[12];

sizeof(class)=?

12) int *p;
i=10;
p=i;
printf("%d",*p);

13) fact(5)
int n;
fact(n)

sum=n*fact(n-1);

NEXT FINITE ELEMENT ANALYSYS QUESTIONS

1) NAME THE EQUATION AND EXPLAIN THE TERMS
A) M/I=F/Y=E/R.
B) mx..+cx.+kx=F(t) ans: sdof mass-spring-dashpot equn.

2) WHAT ARE THE DIFFT.TYPES OF FINITE ELEMENTS.

3) WHAT IS THE SIZE OF STIFFNESS MATRIX FOR A 4 NODED SHELL ELEMENT IN 3-D SPACE.

4) HOW MANY NODES ARE THERE FOR A BEAM ELEMENT ? WHY?

5) WRITE STIFFNESS MATRIX OF TRUSS ELEMENT.

6)WHAT ARE PLANE STRESS AND PLANE STRAIN ELEMENTS

7)WHAT IS MENT BY STRESS SMOTHENING

8)WHAT IS GAUSS POINT

9)WHAT ARE CO AND C1 PROBLEMS
