char c1,c2; c1=197; c2=198; printf("c1=%c,c2=%c ",c1,c2); printf("c1=%d,c2=%d ",c1,c2); return 0;

题目

char c1,c2; c1=197; c2=198; printf("c1=%c,c2=%c ",c1,c2); printf("c1=%d,c2=%d ",c1,c2); return 0;
#include
int main()
{
char c1,c2;
c1=197;
c2=198;
printf("c1=%c,c2=%c ",c1,c2);
printf("c1=%d,c2=%d ",c1,c2);
return 0;
}
运行后为什么是C1=?,C2=?
C1=-59,C2=-58,
