What are pragmas and what are they good for?
main() { int i=5; printf("%d%d%d%d",i++,i--,i); }
what is linkage error when it occurs in c program
print the table 5 in loops
for questions 14,15,16,17 use the following alternatives:a.int b.char.c.string.d.float
main() { int i=0; while(+(+i--)!=0) i-=i++; printf(i); }
code for selection sort?
Why doesn't the code "int a = 1000, b = 1000; long int c = a * b;" work?
What is graph in c?
Which is the best sort method for library management?
What is LINKED LIST? How can you access the last element in a linked list?
what is the output of the following program? main() { int i=-1,j=-1,k=0,l=2,m; m=i++&&j++&&k++||l++; printf("%d %d %d %d %d",i,j,k,l,m); }
C
