Function(i=10); Ans: error 9. #define SWAP(x,y) t=x;x=y;y=t; main() { int x=5,y=6; if (x>y) SWAP(x,y); Printf("x=%d y=%d\n",x,y); } note:- That the function SWAPis not within braces 10. sum(int x) {int t; if(x<=1) return (1); t=sum(x-3)+sum(x-1); return (t); } 11. if 6 is passed to the function, what is the value returned to the calling function. Ans:-9 12. what is int (*ptr)[]()? 13. Main() {int a[]={0,2,4,6,8}; int *ptr; ptr=a; printf("%d", *((char *) ptr+4)); } find output 8 2 4 6 Ans:- 4 14. which takes the same memory space regardless of the type of operating system? Ans:- Char* char int float 15. main() { int I=3; while(I--) {int I=100; I--; Printf("%d", I); } } find output? 100 99 98 99 98 97 99 99 99 error Ans:- 99 99 99 16. main() {char ch; for(ch='0';ch<=255;ch++) printf("%c", ch); } Ans : infinite loop 17. some program using variable b which was not initialized so Ans:- error 18. main() { int i=3; while (i--- ) { int i=100; i----; printf("%d", i); } } a) 99 99 99 b)2 2 2 c) error d) none of the above 19..Size of which data type is same irrespective of operating system. a) char * b) char c) int d) float 20. main() { unsigned char c; for (c=0; c!=256; c+) printf("%d", c); } how many times does the loop will be executed. a) 256 b) 255 c) infinite 21. int (*P[10])( ) Description 5. main() { int val = 50; int *ptr1 = val; int *ptr2 = ptr1; printf("%d %d %d," ++val, *ptr1, *ptr2); *ptr2 = 100; printf("%d %d %d,"++val, *ptr1, *ptr2); } a) 51 50 50 101 100 100 b) 51 51 51 101 101 101 c) error d) none of the above 22. Equivalent Resistance between X & Y 23. Two 230v, 'x' watts power wire are connected in parallel & it is used to heat water when the same is connected in series at same temp what is ratio of time taken by the two. 24. Transformer turns ratio is 1:4 if primary resistance = 25ohms secondary resistance =? 25. Capacitive Reactance = 40 ohms Frequency = 500hz If the freq is reduced to 100hz what is the value of resistance. 26.
