b) 4 c) 6 d) 7 32. Any C program a) must contain at least one function b) need not contain ant function c) needs input data d) none of the above 33. Using goto inside for loop is equivalent to using a) continue b) break c) return d)none of the above 34. The program fragment int a=5, b=2; printf(“%d”,a+++++b); a) prints 7 b)prints 8 c) prints 9 d)none of the above 35. printf(“ab” , “cd”,”ef”); prints a) ab abcdef c) abcdef, followed by garbage value d) none of the above 36. Consider the following program segment. i=6720; j=4; while((i%j)==0) { i=i/j; j=j+1; } On termination j will have the value a) 4 b) 8 c) 9 d) 6720
