scanf("%d",&g);
if(g=1)
{printf("Enter two number:\n");
scanf("%d%d",&b,&c);
printf("%d+%d=%d",b,c,(b+c));}

else if(g=2)
{printf("Enter two number:\n");
scanf("%d%d",&b,&c);
printf("%d-%d=%d",b,c,(b-c));}

else if(g=3)

{printf("Enter two number:\n");
scanf("%d%d",&b,&c);
printf("%d*%d=%d",b,c,(b*c));}

else if(g=4)

{printf("Enter two number:\n");
scanf("%d%d",&b,&c);
printf("%d/%d=%d",b,c,(b/c));}

Answer 1

if (g ==
not g=

= is an assigment operator it give value to g.

== is comparison operator

Answer 2

Don't use = instead of ==

= is an assignment operator, but you are looking for a comparison operator (==)

Answer 3

Oh!Thanks

Answer 4

You're forgetting the symbol of "==" is the same, and "=" is an assignment. When using the IF statement, WHILE or DO-WHILE you need to use "=="
