String Reversed using Functions

#include<stdio.h>

int string_reverse(int l,char s[])
{   int i=0;
   int  j=l-1;
   int t;
    while(i<j)
    {
        t=s[i];
        s[i]=s[j];
        s[j]=t;
        i++;
        j--;
    }
	    return s;
}

int string_length(char s[])
{  
    int j=0;
	   while(s[j]!='\0')
    {
        j++;
    }
	
    return j;
	
}

int main()
{   

    char a[100],t;
    int l;
    printf("Enter a string\n");
    gets(a);
    
    l=string_length(a);
    string_reverse(l,a);
    printf("The reversed string is: ");
    puts(a);
