Answer / saddi srikanth
if x=14, y=18
x=x+y;
now x=14+18=32;
y=x-y;
now y=32-18=14;
now again y=14
x=x-y;
now x=32-14=18
final answer is:
x=18, and y=14
u can try this formule by taking any values for x and y.

main() { void swap(); int x=10,y=8; swap(&x,&y); printf("x=%d y=%d",x,y); } void swap(int *a, int *b) { *a ^= *b, *b ^= *a, *a ^= *b; }

How do you create a really large matrix (i.e. 3500x3500) in C without having the program crash? I can only reach up to 2500. It must have something to do with lack of memory. Please help!

Link list in reverse order.
what is the output of the below program & why ? #include<stdio.h> void main() { int a=10,b=20,c=30; printf("%d",scanf("%d%d%d",&a,&b,&c)); }
#include<stdio.h> int main() { int a=3,post,pre; post= a++ * a++ * a++; a=3; pre= ++a * ++a * ++a; printf("post=%d pre=%d",post,pre); return 0; }
#include<stdio.h> main() { int i=1,j=2; switch(i) { case 1: printf("GOOD"); break; case j: printf("BAD"); break; } }
enum colors {BLACK,BLUE,GREEN} main() { printf("%d..%d..%d",BLACK,BLUE,GREEN); return(1); }
char *someFun() { char *temp = “string constant"; return temp; } int main() { puts(someFun()); }
write the function. if all the character in string B appear in string A, return true, otherwise return false.
