做一个十进制转化二级制 和五进制和八进制得转化 但是老是显示too many initializers

[氵景页（Muzi）]

#include<stdio.h>
int change(int a,int b)
{
int s[20],i=0,rem;
if(b=2)
{ while(a){
rem=a%2;
a=a/2;
s[i++]=rem;
}
printf("十进制数%d转换为%d进制后为：");
while(i>0)
printf("%d",s[--i]);
printf("\n"); }
else if(b=5)
{while(a){
rem=a%5;
a=a/5;
s[i++]=rem;
}
printf("十进制数%d转换为%d进制后为：");
while(i>0)
printf("%d",s[--i]);
printf("\n"); }
else if (b=8)
{
while(a){
rem=a%8;
a=a/8;
s[i++]=rem;
}
printf("十进制数%d转换为%d进制后为：");
while(i>0)
printf("%d",s[--i]);
printf("\n");

}
else
printf("\n");}
int main()
{
int a,b;
printf("请输入一个十进制数 :");
scanf("%d",&a);
printf("\n");
printf("要转换成的进制为:");
scanf("%d",&b);
printf("\n");
int change(a,b);
return 0;

}

[真相重于对错]

int change(a,b); ===》 change(a,b);

[永远的追梦人]

printf("十进制数%d转换为%d进制后为：");  后面是不是少两个参数

#include<stdio.h>  
int change(int a,int b)
{
    int s[20],i=0,rem;  
    int oa = a;
    if(b==2)
    { while(a){   
        rem=a%2;   
        a=a/2;   
        s[i++]=rem;
    }  
    printf("十进制数%d转换为%d进制后为：",oa,b);  
    while(i>0)   
        printf("%d",s[--i]);  
    printf("\n"); }
    else if(b==5)
    {while(a){   
        rem=a%5;   
        a=a/5;   
        s[i++]=rem;
    }  
    printf("十进制数%d转换为%d进制后为：", oa, b);
    while(i>0)   
        printf("%d",s[--i]);  
    printf("\n"); }
    else if (b==8)
    {
        while(a){   
            rem=a%8;   
            a=a/8;   
            s[i++]=rem;
        }  
        printf("十进制数%d转换为%d进制后为：", oa, b);
        while(i>0)   
            printf("%d",s[--i]);  
        printf("\n"); 

    }
    else
        printf("\n");
    return 0;
}
int main()
{
    int a,b;
    printf("请输入一个十进制数 :");
    scanf("%d",&a);
    printf("\n");
    printf("要转换成的进制为:");
    scanf("%d",&b);
    printf("\n");
    return change(a,b);
}

修了些明显的语法错误，这个能通过编译了
