GDPU C语言 小测1

1.输出菱形

#include <stdio.h>
#include <math.h>int main(){int n,j,i;scanf("%d",&n);for(i = 1; i <= n/2+1; i++){for(j = 1; j <= n/2+1-i; j++){printf(" ");	}for(j = 1; j <= 2*i-1; j++)printf("*");printf("\n");}	for(i = 1; i <= n/2; i++){for(j = 1; j <= i;j++)printf(" ");for(j = 1; j <= n-2*i;j++)printf("*");printf("\n");}return 0;
}

2. 求分段值

#include <stdio.h>
#include <math.h>int main(){
//	int x,j,i;double x,y;scanf("%lf",&x);y = x;if(x >= 1 && x < 10)y = x-1;else if(x >= 10)y = 3*x -11.0;printf("y=%.2lf",y);return 0;
}

3. 分队列

#include <stdio.h>
#include <math.h>int main(){
//	int x,j,i;int n,i;scanf("%d",&n);for(i =1; i <= n; i+=2){printf("%d ",i);}return 0;
}
