Xt1-5

#include int main ( )

{ printf (\ printf(\ printf (\ return 0; }

Xt1-6

#include int main()

{int a,b,c,max;

printf(\ scanf(\ max=a; if (max

max=c;

Xt3-1

#include #include int main() {float p,r,n; r=0.1;

n=10;

p=pow(1+r,n); printf(\ return 0; }

Xt3-4(1)

#include int main() {int c1,c2; c1=197;

c2=198;

printf(\ printf(\，c2=%d\\n\

return 0; }

Xt3-4(2)

#include int main() {int a,b; float x,y; char c1,c2;

scanf(\ scanf(\ scanf(\

printf(\ return 0; }

Xt3-4(3)

#include int main()

{char c1='C',c2='h',c3='i',c4='n',c5='a'; c1=c1+4; c2=c2+4; c3=c3+4; c4=c4+4; c5=c5+4;

printf(\ return 0; }

Xt3-4(4)

#include int main ()

{float h,r,l,s,sq,vq,vz; float pi=3.141526;

printf(\请输入圆半径r，圆柱高h∶\

scanf(\要求输入圆半径r和圆柱高h l=2*pi*r; //计算圆周长l s=r*r*pi; //计算圆面积s

sq=4*pi*r*r; //计算圆球表面积sq vq=3.0/4.0*pi*r*r*r; //计算圆球体积vq vz=pi*r*r*h; //计算圆柱体积vz printf(\圆周长为: l=%6.2f\\n\ printf(\圆面积为: s=%6.2f\\n\ printf(\圆球表面积为: sq=%6.2f\\n\

printf(\圆球体积为: v=%6.2f\\n\ printf(\圆柱体积为: vz=%6.2f\\n\ return 0; }

Xt3-4(5)

#include int main() {

char c1,c2;

printf(\请输入两个字符c1,c2:\c1=getchar(); c2=getchar();

printf(\用putchar语句输出结果为:\putchar(c1);

putchar(c2); printf(\

printf(\用printf语句输出结果为:\printf(\return 0; }

Xt3-4(6)

#include int main() {

int c1,c2; //整型定义 printf(\请输入两个整数c1,c2:\ scanf(\ printf(\按字符输出结果:\\n\ printf(\

printf(\按ASCII码输出结果为:\\n\ printf(\ return 0; }

Xt3-4(7)

#include int main()

{

char c1,c2; //定义字符型变量 int i1,i2; //定义整型变量 printf(\请输入两个字符c1,c2:\ scanf(\

i1=c1; //赋值给整型变量 i2=c2;

printf(\按字符输出结果:\\n\ printf(\

printf(\按整数输出结果:\\n\ printf(\ return 0; }

Xt3-4(8)

#include int main()

{

char c1,c2; // int i1,i2; // printf(\请输入两个整数i1,i2:\

scanf(\

c1=i1; // c2=i2;

printf(\按字符输出结果:\\n\ printf(\ printf(\按整数输出结果:\\n\ printf(\ return 0; }

Xt3-4(9)

#include int main() {

int a,b,c;

printf(\请输入三个整数:\ scanf(\ if (a

if (b

printf(\ else

printf(\ else if (a

printf(\ else

printf(\ return 0; }

定义为字符型 定义为整型 将整数赋值给字符变量
