c language string processing

Find the number from the string and formatted

1- for formatting
2- parsing array generated

#include<stdio.h>
int main() {
	//格式化 
	//格式化样例1-22-10-11-2-0-32-
	char s[100];
	char str[100]="3hui 242 32 - 34 43";
	char c;
	int i,j=0;	
	for(i=0;i<strlen(str);i++){
		c=str[i];
		if(c>='0'&&c<='9'){
					if(i==strlen(str)-1){
						s[j++]=c;
						s[j++]='-';
					}else{
						if(str[i+1]<'0'||str[i+1]>'9'){
							s[j++]=c;
							s[j++]='-';
						}else{
							s[j++]=c;
						}					
					}
		}
	}
	//
	//解析生成数组 
	int fbi[100]={0};
	int n=0,m=0;
	int begin=0,p=0;
	for(i=0;i<strlen(s);i++){
		if(s[i]=='-'){
			p=i-begin;
			for(j=begin;j<i;j++){
				fbi[m]+=(s[j]-48)*pow(10,p-1);
				p--;
			} 
			begin=i+1;
			m++;
		}
	}
	return 0;
