为什么不是'；fread、fwrite或fseek是否适合我C
我有下面的问题，我一直在努力解决，但我仍然不能 我有一个二进制文件，其中包含1000个0-9之间的随机整数，我使用的代码是：为什么不是'；fread、fwrite或fseek是否适合我C,c,file,binary,fwrite,fseek,C,File,Binary,Fwrite,Fseek,我有下面的问题，我一直在努力解决，但我仍然不能 我有一个二进制文件，其中包含1000个0-9之间的随机整数，我使用的代码是： int main() { FILE *fp; int r, i; char fp_string[600] = "/Users/mac/Library/Mobile Documents/com~apple~CloudDocs/College/Program With Persistent Data/Lab 3/num1000.bin"; fp = fopen(fp_s
