#include <stdio.h> int main() { int a=3; int b=2; int c=a+b; printf("сумма С = \n", c); }
The program adds two integers a and b, stores the result in c, and tries to print it.

- The printf format string contains no format specifier such as %d, so the value of c is never printed; add the correct specifier where you want the number to appear.
- The newline is placed before the value would be printed, so even after adding a specifier, check the order of the text and the placeholder in the string.
