C语言在字符串str中删除所有字符c

Question

在字符串str中删除所有字符c，返回数组元素个数
救命每次返回字符串的时候怎么都少掉第一位啊
#include <stdio.h>
#include <string.h>
int StrDelChar(char str[], char c){
int p=0,q=0;
while((str+p)!='\0'){
p++;
if((str+p)!=c){
(str+(q++))=(str+p);
}
}
return q;
}
int main(){
char s[1000],c;
int n, i = 0;
while ((s[i++] = getchar()) != '\n');
s[i - 1] = 0;
c = getchar();
n = StrDelChar(s, c);
printf("%d %s", n,s);
return 0;
}

#include <stdio.h>
#include <string.h>
int StrDelChar(char str[], char c){
int p=0,q=0;
while((str+p)!='\0'){
if((str+p)!=c){
(str+(q++))=(str+p);
}

p++;

}
return q;
}
int main(){
char s[1000],c;
int n, i = 0;
while ((s[i++] = getchar()) != '\n');
s[i - 1] = 0;
c = getchar();
n = StrDelChar(s, c);
printf("%d %s", n,s);
return 0;
