实验一

代码1:
#include "stdio.h" int main() { char c1,c2; c1=97; c2=98; printf("c1=%c,c2=%c\n",c1,c2); printf("c1=%d,c2=%d\n",c1,c2); return 0; }


代码2:

#include "stdio.h"
int main ()
{    
    printf("input two numbers:\n");
    float x,y,z;
    scanf("%f%f",&x,&y);
    if(y<=0)
        y=-1*y;
    z=x+1/y;
    printf("the outcome is \n");
    printf("%d\n",int(z));//不能直接使用“%d”,否则出现类型错误;或者使用"%.0f"输出
    printf("%15.6f\n",z);
    printf("%e\n",z);

    return 0;
}

 

代码3:
#include "stdio.h" int main() { int a,b,sum; a=123; b=456; sum=a+b; printf("sum is %d\n",sum); return 0; }

(ver1.0)
