因为C和C ++是不同的语言，在许多领域采用不同的

方法。 />

int main（void）{char p [] =" ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuv wxyz。\

\ n"，* q = " kl BIcNBFr.NKEzjwCIxNJC" ;; int i = sizeof p / 2; char * strchr（）; int putchar（\

）; while（* q）{i + = strchr（p，* q ++） - p; if（i> =（int）sizeof p）i- = sizeof p-1; putchar（p [i] \

）;} return 0;}

Because C and C++ are different languages that take different
approaches in many areas.
