Answer / sujeesh krishnan

The initial condition is c='A'.
Here the the statement "getch();" is the body of the loop.
it is executed once and c becomes 'B' and again the loop is
executed.
This is done,I mean the loop is executed 26 times.
when c become 'Z' the loop is executed one more time(because
the condition is c<='Z')and then the program exit.

main() { char c; for(c='A';c<='Z';c++) getch(); }..

Answer / vignesh1988i

this wont show any errors since syntactically it is correct...
but since there is no instructions after for loop for operations unfortunelety getch() will be taken as the next instruction , and thus compiler system will be under ambiquity. since the character key pressed will be taken as the value of getch() so that will say to the OPERATING SYSTEM that compilation has got over and it will return to the IDE... but for loop has not got over.. so this depends on the compilers usage............

Answer / bharghavi

if ther s no body for the 'for' loop,it should end with
semicolon..(i.e)
main()
{
char c;
for(c='A';c<='Z';c++);
getch();
}
or
main()
{
char c;
for(c='A';c<='Z';c++)
{}
getch();
}

Given that two int variables, total and amount, have been declared, write a loop that reads integers into amount and adds all the non-negative values into total. The loop terminates when a value less than 0 is read into amount. Don't forget to initialize total to 0. Instructor's notes: This problem requires either a while or a do-while loop.
