C Primer Plus 练习 9-2

题目：设计函数chline(ch,i,j)，实现指定字符在i列到j列的输出，并用一个简单的驱动程序测试该函数。

//9-2#include<stdio.h>void chline(char,int,int);int main(void){char ch;int i, j;printf("Please input the character:");ch = getchar();printf("Please input the limit of line from little to big: ");scanf_s("%d %d", &i, &j);chline(ch, i, j);return 0;}void chline(char ch, int i, int j){int k;for (k = 0; k < i-1; k++)putchar('#');for (k = i-1; k < j; k++)putchar(ch);}
