Re: [TUHS] A c program problem

Sorry, I won't be sending it next time. Oh oh, maybe I forgot to add; . I typed the code on the book, and the result of running the book was 5050, but the compiler was 100. | | cc | | 邮箱：caipenghui_c(a)163.com | 签名由 网易邮箱大师 定制 On 08/22/2018 22:21, Dan Cross wrote: Note, TUHS probably isn't the *best* forum to ask for help with basic C programs. :-) That said, I suspect you mis-transcribed the program and that the line, `sum = sum + 1;` should be `sum = sum + i;`, or more idiomatically, `sum += i;`. Indeed, the whole program could be written: #include <stdio.h> int main(void) { int i, sum = 0; for (i = 1; i <= 100; i++) sum += i; printf("%d\n", sum); return 0; } If you're using a C99 or later compiler, you can be slightly more succinct: #include <stdio.h> int main(void) { int sum = 0; for (int i = 1; i <= 100; i++) sum += i; printf("%d\n", sum); return 0; } Hope that helps! - Dan C.
