Answer / susie
Answer :
-1
Explanation:
Unary + is the only dummy operator in C. So it has no effect
on the expression and now the while loop is, while(i--!=0)
which is false and so breaks out of while loop. The value –1
is printed due to the post-decrement operator.

Answer / govind verma
output will be -1.... because inwhile +(+i--)!=0 () have higher precedence then control goes to in parenthses and unary plus and ++ have the same precedece in table then we chek the associativty which is right to left i++ is evaluate first then the value of i will not chang withn a same expression because its a post fix increment now expression become +(+0)!=0 and unary plus have no effect then expression look lyk 0!=0 this condition is false then while block of code will not execute and nw i become -1 and we try to print like this printf("%d",-1); then output will -1

void main() { int i=5; printf("%d",i+++++i); }
given integer number,write a program that displays the number as follows: First line :all digits second line : all except the first digit . . . . Last line : the last digit
main() { int i; clrscr(); printf("%d", &i)+1; scanf("%d", i)-1; } a. Runtime error. b. Runtime error. Access violation. c. Compile error. Illegal syntax d. None of the above
main() { int i, j, *p; i = 25; j = 100; p = &i; // Address of i is assigned to pointer p printf("%f", i/(*p) ); // i is divided by pointer p } a. Runtime error. b. 1.00000 c. Compile error d. 0.00000
In the following pgm add a stmt in the function fun such that the address of 'a' gets stored in 'j'. main(){ int * j; void fun(int **); fun(&j); } void fun(int **k) { int a =0; /* add a stmt here*/ }
