# Include <stdio. h> int main () {int I = 0, j = 0, num = 0, k = 0; printf ("Enter the number of rows in the Yang Hui triangle to be output :"); scanf ("% d", & num); for (I = 1; I <= num; I ++) {k = 1; // each line must start with 1, therefore, define K outside the L2 loop for (j = 1; j <= I; j ++) {printf ("% 5d", k ); k = k * (I-j)/j;} printf ("\ n");} return 0 ;}

 

Note: If the number of input rows overflows, you can define the integer type as a long integer.
