实验一编程求37+29的值,实****VC环境。#include<>voidmain(){ inta,b,sum;a=37; b=29;sum=a+b;printf("sum=%d",sum);}从键盘输入三个整数,求出最大数并输出。#include<>voidmain(){ inta,b,c,y; intmax(intx,inty); printf("inputa,b,andc:"); scanf("%d,%d,%d",&a,&b,&c); y=max(a,b); y=max(y,c); printf("\nmax=%d\n",y);}intmax(intx,inty){intz;if(x>y)z=x;elsez=y;return(z);} 通过上机实践,运行下列程序并分析输出结果。A程序代码#include<>voidmain(){ charch='a'; printf("%c对应的ASCII码是:%d\n",ch,ch); }程序输出结果:a对应的ASC||码是:97B程序代码#include<>voidmain(){ inta=168; floatb=; floatx=,y; printf("a=%5d\n",a); printf("a=%-5d\n",a); printf("b=%\n",b); printf("b=%e\n",b); y=(int)(x*100+)/; printf("x=f,y=%f\n",x,y);}程序输出结果:a=168a=168b==+002x=f,y=#include<>voidmain(){ inta=168; printf("十进制数%d对应的八进制数是%o\n",a,a); printf("十进制数%d对应的十六进制数是%x\n",a,a);}程序输出结果:=,b=,c=,计算s=-4ac的结果并输出。#include<>voidmain(){ floata,b,c,s; a=; b=; c=; s=b*b-4*a*c; printf("s的值是%f\n",s);},计算出该学生的成绩总分和平均分。#include<>voidmain(){intmath,english,c_program;floatsum,average;printf("inputmath,english,c_program:");scanf("%d,%d,%d",&math,&english,&c_program);sum=math+english+c_program;average=sum/3;printf("sum=%.0f,average=%.5f",sum,average);},计算圆的面积,.#include<>intmain(){ floatr,s; printf("请输入半径:"); scanf("%f",&r); s=*r*r; printf("圆的面积为%.6f",s);},将其个位数和十位数互换后变成一个新的数,输出这个数。#include<>intmain(void){intn,a,b;printf("inputn:");scanf("%d",&n);b=n%10;a=n/10;n=b*10+a;printf("%d\n",n);return0;},将两数的值互换后输出新值。#include<>voidmain(){ intx,y,t; scanf("%d%d",&x,&y); t=x; x=y; y=t; printf("x=%d,y=%d\n",x,y);},求出其中的较小值输出。#include<>intmain(){ inta,b,min; printf("请输入a,b:\n"); scanf("%d,%d",&a,&b);if(a<b)min=a;elsemin=b;printf("最小值是%d\n",min);return0;}。+2xx<2Y=f(x)=2x-1x>=2#include<>intmain(void){ doublex,y; s
