C language bubble arrangement problem

Bubbling is to pick the smallest number from a sequence of numbers and exchange it with the first number, you have too many mistakes in this program.

for(j=1;j<=i;j++)

for(k=1;k<=i-j;k++)

if(num[i]>num[i+1])

t=num[i];

num[i]=num[i+1];

num[i+1]=t;

What is the use of using j and k as circulation factors, but the changes in it have nothing to do with j and k? And your ii, which will cause confusion in reading, and too many variable references.

#include

int main(void)

int num[100],i=0,n,j,k,t,ii;

char key;

printf("Please enter n digits, a negative number indicates that the input is complete");

do ++i;

printf("%d. -",i);

scanf("%d",&n);

fflush(stdin);

num[i]=n;

while(num[i]>0);

i--;//

for(j=1;j<=i;j++)

for(k=1;k<=i-j;k++)

if(num[k]>num[k+1]) //t=num[k];

num[k]=num[k+1];

num[k+1]=t;

for(ii=i,i=2;i<=ii;i++)printf("%d ",num[i]);In terms of procedure.

if(num[i]>num[i+1])

t=num[i];

num[i]=num[i+1];

num[i+1]=t;

where i should be replaced by k, i.e., read as follows:

if(num[k]>num[k+1])

t=num[k];

num[k]=num[k+1];

num[k+1]=t;

In addition, it is proposed that the last part of the procedure be changed to the following form:

for(ii=i,i=2;i<=ii;i++)printf("%d ",num[i]);
