小学生测试题c语言,用c语言编写 小学数学考试题1）任意生成5道题，每道题有两个运算数，且都在1到100间，它们参与的运算是＋－×÷中的任意一种。2）显示生成的5道题。3）每给出1道题目后，要提示用户...

main()

{

int a[5],b[5],c[5];

flost q[5];

int i;

char d[5];

for(i=0;i<5;i++)

{

a[i]=rand()%100;

b[i]=rand()%100;

c[i]=rand()%4;

if(a[i])

a[i]++;

if(a[i])

a[i]++;

switch(c[i]+1)

{

case 1: d[i]='+';

case 2: d[i]='-';

case 3: d[i]='*';

case 4: d[i]='÷';

}

}

for(i=0;i<5;i++)

{

printf("The %d problem:\n");

printf("%d%c%d=",a[i],d[i],b[i]);

scanf("%d",&q[i]);

system("cls");

printf("The %d problem:\n");

printf("%d%c%d=%d",a[i],d[i],b[i],q[i]);

switch(c[i]+1)

{

case 1:

{

if(a[i]+b[i]==q[i])

printf("yes");

else

printf("not");

}

case 2:

{

if(a[i]-b[i]==q[i])

printf("yes");

else

printf("not");

}

case 3:

{

if(a[i]*b[i]==q[i])

printf("yes");

else

printf("not");

}

case 1:

{

if(a[i]*1.0/b[i]==q[i])

printf("yes");

else

printf("not");

}

}

}

}
