    Sting and Char Funny Problem

    I try to get Strng first then get Character from user. But it wont work, the process of getting character will be skipped. But when i try get char first then string, it works! Please assist. TY
    Code:
    #include <stdio.h>
    
    int main (){
    	
    	char singleChar;
    	char text[30]={0};
    	int count;
    	
    	printf("String:");
    	scanf("%s", text);
    	
    	printf("Character:");
    	scanf("%c", &singleChar);
    	//singleChar will automatically proceed without getting input from user
    	//But when Char is get before String, No problem.
    	
    //Test Result
    	printf("\nCharacter: %c\n",singleChar);
    	printf("String: %s\n",text);
    
    }

    You're being tripped up by the newline char that scanf() leaves behind in the income stream (keyboard buffer).

    Add:
    getchar();

    After the first scanf(), and all will be well.

    Referring to message 1...
    On line 13 ad a single space between the " and %c ... scanf(" %c".... This will tell scanf to skip over anything left in the input buffer.
