Test the program with the following values: 68, 150, 212, 0, -22, -200 (degree Fahrenheit).

Question 5

What will be output of the following program?

#include<stdio.h> int main(){ int i=5,j; j=++i+++i+++i; printf("%d %d",i,j); return 0; }

Got an error for this ( j=++i+++i+++i;) But this gives an answer j=++i + ++i + ++i;

Question 6

What will be output of the following program?

#include<stdio.h> int main(){ int i=1; i=2+2*i++; printf("%d",i); return 0; }

Question 7

What will be output of the following program?

#include<stdio.h> int main(){ int a=2,b=7,c=10; c=a==b; printf("%d",c); return 0; }

Question 8

What will be output of the following program?

#include<stdio.h> int main(){ int a=0,b=10; if(a=0){ printf("true"); } else{ printf("false"); } return 0; }

Question 9

What will be output of the following program?

#include<stdio.h> int main(){ int a; a=015 + 0x71 +5; printf("%d",a); return 0; }

Question 10

What will be output of the following program?

#include<stdio.h> int main(){ int i=5; int a=++i + ++i + ++i; printf("%d",a); return 0; }
