答案如下：仅供参考
1.

#include <stdio.h>

main()
{
float c;
float f;
printf("Input a value:");
scanf("%f",&c);
f=(9.0/5)*c+32;
printf("%f\n",f);
}


2.

#include <stdio.h>
#define PI 3.14159
void main()
{
float r,h;
float l,s,v;
printf("Input two values like this:1.2,2.3\n");
scanf("%f,%f",&r,&h);
l=2*PI*r;
s=PI*r*r;
v=PI*r*r*h;

printf("l=%f,s=%f,v=%f\n",l,s,v);
}


3.

#include <stdio.h>

void main()
{
char c;
printf("Input a char:");
scanf("%c",&c);
printf("The ASCII of the char '%c' is:%d\n",c,c);
}
